PR is merged.

This provides a type-safe way to simplify package loader installation
code since we don't need special checks for games that don't use
package loaders but depend on profiles.

This is to avoid confusion by unifying the naming with the other
PackageInstaller implementations. The convention is to name the mod
loader installers as FooInstaller and the mod installers as
FooPluginInstaller.

- Make internal helper method private
- Rename it to resolveFileTreeInstall as it's not exclusive for BepInEx
- Remove R2Error from helper's return type as no code path returns
  anything but undefined
- Remove unnecessary Promise.resolve as the helper is marked async

This is a step on the path to make InstallRulePluginInstaller support
all four methods of PackageInstaller class.

InstallRuleInstaller class was recently renamed to
InstallRulePluginInstaller to match the conventions in the codebase.
Rename file to match the exported class.

- Make Baby Steps visible now that the mod loader problem is resolved
- Replace obsolote Beetleball playtest version with demo version

Melonloader v0.7.2. was released recently and according to reports
works fine with the demo version of the game. There's no longer need to
shepherd the users to use older version.

Ecosystem sync

Missing await when untinstalling the old version caused installing the
new version to fail due to files being in use.
