Pat to GitHub apps two

[chidozieononiwu]

This pull request introduces improvements to the GitHub authentication flow in the CI/CD pipeline, enhancing token generation, handling, and usage across various pipeline templates and scripts. The main changes add support for exporting the GitHub token as an output variable, improve robustness in handling installation owners, and update pipeline stages to use the new token flow.

Enhancements to GitHub Token Handling:

• eng/common/scripts/login-to-github.ps1:

  • Added the ExportAsOutputVariable parameter to allow exporting the GitHub token as an Azure DevOps output variable for downstream jobs. [1] [2]
  • Improved handling of InstallationTokenOwners, including normalization and more robust matching logic for GitHub App installations. [1] [2]
  • Refactored the main script logic into Invoke-LoginToGitHub and ensured test runs are skipped.
  • Added a utility function Get-PropertyValue for safer property access.

• eng/common/pipelines/templates/steps/login-to-github.yml:

  • Added the ExportAsOutputVariable parameter and passed it through to the script. [1] [2]

Pipeline Integration:

• Updated pipeline templates (publish.yml, publish-extension.yml, vscode-publish-integration.yml) to:
  • Insert a new job or step to generate the GitHub token using the enhanced script and export it as an output variable. [1] [2] [3]
  • Pass the generated GH_TOKEN to subsequent jobs and tasks instead of using the previous azuresdk-github-pat variable. [1] [2] [3] [4]

Other Minor Changes:

• Improved documentation and parameter descriptions in the PowerShell script.
• Minor whitespace and formatting changes in pipeline YAML files.

These changes make the pipeline more secure, flexible, and maintainable by standardizing GitHub token usage and improving compatibility with Azure DevOps output variables.

Pull request overview

This PR updates the Azure DevOps release/publish pipeline templates to switch GitHub CLI authentication from a stored PAT to a GitHub App installation token minted at runtime (via eng/common/scripts/login-to-github.ps1), aiming to standardize token handling across jobs and stages.

Changes:

• Adds ExportAsOutputVariable support to login-to-github.ps1 and plumbs it through the login-to-github.yml step template.
• Updates publishing stage templates to generate a GitHub token and pass it to PR-commenting and release-related steps.
• Replaces $(azuresdk-github-pat) with $(GH_TOKEN) in the extension release step template.
