Migrates the project to .NET 9.0 and updates core dependencies.

This includes:
- Upgrading target frameworks and SDK versions to .NET 9.0
- Updating NuGet dependencies to latest versions (NLog, xunit, coverlet, Microsoft.NET.Test.Sdk, ConfigureAwaitChecker.Analyzer)
- Bumping plugin version to 1.9.0.0
- Minor fix in `SimpleHttpClient.DisposeAsync` for `ValueTask` handling
- Qualifying `OrderedDictionary` namespace in Reddit components for clarity
- Adapting `BotContext` for robust `Bot.OwnedPackages` access, using reflection for fallback

This upgrade ensures compatibility with the latest .NET runtime and incorporates recent improvements from dependency updates.

Improve README clarity, update submodule references, and fix namespace spelling.

This commit addresses several issues raised in #121:

*   Enhanced the README for better understanding and improved formatting.
*   Corrected the submodule path and updated the resource folder name.
*   Updated the ArchiSteamFarm subproject to the latest commit.  (Note: This submodule was previously reported as 404, this commit should resolve this.)
*   Fixed the namespace spelling from 'ASFExtentions' to 'ASFExtensions'.
*   Added VSCode settings to ignore pull request branches from main.
*   Improved error handling in CollectGamesOnClock method for scheduled free games.

Conflicts in .gitmodules and ArchiSteamFarm were resolved.

The pull request primarily focuses on:

* **Namespace Corrections:**  Changing `ASFExtentions` to `ASFExtensions` throughout the codebase. This appears to be a correction of a consistent typo.
* **Code Style and Formatting:** Minor formatting adjustments in various files, including whitespace and XML formatting.
* **Documentation Improvements:**  Spelling and grammar corrections in comments and the README.md file, along with clarifications and updates to the documentation.
* **Resource Folder Renaming:** Renaming the `Resouces` folder to `Resources` in the project file and code. This seems to be another typo correction.
* **VSCode Settings:** Adding a `.vscode/settings.json` file for development environment configuration, specifically to ignore pull requests from the "main" branch in the GitHub Pull Requests extension.
* **Minor Bug Fix/Improvement in `ASFFreeGamesPlugin.cs`:**
    * Correcting the bot instance passed to `OnBotCommand` in the scheduled task from `null!` to `reorderedBots[0]`.
    * Adding a try-catch block to handle potential exceptions during scheduled free game collection.
* **Redlib Instance List Update:** Adding a new `Resources/redlib_instances.json` file, which seems to be an updated list of Redlib instances.

**File-by-File Analysis:**

* **`.gitignore`**:  Spelling correction in comments ("checkin" to "check in"). **Safe and intended.**
* **`.vscode/settings.json`**:  VSCode specific settings, ignoring "main" branch PRs. **Safe and development-related.**
* **`ASFFreeGames.Tests/GameIdentifierParserTests.cs` & `ASFFreeGames.Tests/GameIdentifierTests.cs`**: Namespace correction (`ASFExtentions` to `ASFExtensions`). **Safe and likely a typo fix.**
* **`ASFFreeGames.sln`**:  Minor formatting change (removing a blank line). **Safe and cosmetic.**
* **`ASFFreeGames/ASFExtentions/Bot`, `ASFFreeGames/ASFExtentions/Games`, `ASFFreeGames/AppLists`, `ASFFreeGames/Commands`, `ASFFreeGames/Configurations`, `ASFFreeGames/ContextRegistry`, `ASFFreeGames/Redlib`, `ASFFreeGames/Utils`**:  Consistent namespace corrections (`ASFExtentions` to `ASFExtensions`). **Safe and likely typo fixes throughout the project.**
* **`ASFFreeGames/ASFFreeGames.csproj`**: Folder name correction (`Resouces` to `Resources`). **Safe and likely a typo fix. Ensure the folder is renamed accordingly in the filesystem if merging.**
* **`ASFFreeGames/ASFFreeGames.csproj.DotSettings`**: Minor XML formatting change. **Safe and cosmetic.**
* **`ASFFreeGames/ASFFreeGamesPlugin.cs`**:
    * Namespace corrections.
    * Corrected bot instance in scheduled task (`null!` to `reorderedBots[0]`). **Bug fix.**
    * Added try-catch for scheduled task. **Improvement - error handling.**
    * Removed unnecessary `#pragma warning disable/restore` which is good, likely the code is now correct async.
* **`ASFFreeGames/Redlib/Instances/RedlibInstanceList.cs`**:
    * Resource path correction (`Resouces` to `Resources`).
    * Code style improvements.
    * Constructor parameter change (field assignment). **Refactoring, safe.**
    * Using `new List<Uri>()` instead of `[]` when instances are null. **Minor improvement in code clarity.**
* **`ASFFreeGames/Resources/redlib_instances.json`**: New file containing a list of Redlib instances. **Likely an intended update to the default instance list. Review the URLs to ensure they are trustworthy.**
* **`ASFFreeGames/Utils/LoggerFilter.cs` & `ASFFreeGames/Utils/RandomUtils.cs`**: Code style, formatting, documentation improvements, and minor variable name changes. **Safe and improves code quality.**
* **`README.md`**: Documentation improvements, spelling/grammar fixes, command clarifications, proxy setup, and FAQ updates. **Safe and beneficial for users.**

The `bot` parameter in `OnBotCommand` is now nullable (`Bot? bot`), allowing the function to be called without specifying a bot.  This is necessary for scenarios like scheduled free game collection where a specific bot context might not be relevant. The call to `OnBotCommand` in `CollectScheduledFreeGames` has been updated to pass `null` for the bot parameter.

…age ownership checks.

This includes:
- Direct access and reflection fallback for robustness.
- Caching with hot-reload awareness for performance.
- Integration into BotContext for improved ownership checks.
- Cache clearing on bot disconnect in ASFFreeGamesPlugin.
