Pull request overview
Updates the VMR synchronization pipeline to authenticate GitHub pushes using a short-lived GitHub App installation token (minted via Key Vault signing) instead of a long-lived push PAT, aligning the release/8.0.1xx branch with the intended auth model for dotnet/dotnet synchronization.
Changes:
- Adds a workaround step to copy
Get-GitHubAppToken.ps1and its logging dependency into$(System.DefaultWorkingDirectory)/eng/commonso the shared token-minting template can run under multi-checkout layout. - Calls the shared
/eng/common/templates-official/steps/get-github-app-token.ymlto mint an installation token from Key Vault. - Switches
darc vmr pushto use the generated token via--github-pat '$(vmrPushToken)'.
