Getting ready for 10.2 release

----
#### AI description  (iteration 1)
#### PR Classification
This pull request prepares the project for the 10.2 release by updating dependency versions and refining pipeline configurations.

#### PR Summary
The update bumps numerous internal dependency versions (from 9.0.11/10.0.1 to 9.0.12/10.0.2), adjusts release stabilization settings, revises internal NuGet source mappings, and updates CI/CD tasks.
- `eng/Version.Details.xml` and `eng/Versions.props`: Upgraded many Microsoft and runtime dependencies and updated stabilization/release build flags.
- `azure-pipelines.yml`: Removed the code coverage stage and updated stage dependencies.
- `NuGet.config`: Removed the package source mapping block and adjusted internal package source settings.
- `eng/pipelines/templates/BuildAndTest.yml`: Added tasks to set up private feed credentials and commented out integration tests.
- `Directory.Build.props`: Disabled the NU1507 warning for internal feeds.

…align with MCP packages

Backports #7170 into the release branch as it was merged into main after the snap.

This will effectively prevent the 10.2 release from publishing the package since it hard codes the version to a version that has already been published, but it gets the release branch aligned with the release/10.1 branch that has this change as well.

…ionReport (#7108)

* Add .npmrc next to package.json

The .npmrc is not transitively looked up in parent directories like other config files, it needs to be next to the package.json

Also remove the always-auth entry since it is deprecated/unused in npm and will be removed: actions/setup-node#1305

* Don't run npm install in CI, it should only be run locally by an authenticated developer

* Update vulnerable npm packages

* Make sure we're using AzDO feed in package-lock.json

* Add UpdateNpmDependencies.ps1 script
