Automate NOTICE.txt updates via pull request

[Copilot]

The build-notice.yml pipeline generates an updated NOTICE.txt file but requires manual PR creation to commit changes back to the repository.

Changes:

• Added create-pull-request.yml template to automatically create PRs with updated NOTICE.txt
  • Branch: eng/update-notice-txt
  • Force push enabled to update existing PR if present
  • Commit message includes build URL for traceability

Implementation:

# Create a PR with the updated NOTICE.txt file
- template: /eng/common/pipelines/templates/steps/create-pull-request.yml
  parameters:
    PushArgs: -f
    PRBranchName: eng/update-notice-txt
    CommitMsg: Update NOTICE.txt from $(System.CollectionUri)$(System.TeamProject)/_build/results?buildId=$(Build.BuildId)
    PRTitle: Update NOTICE.txt

The create-pull-request.yml template handles git authentication internally, so no separate credential configuration is needed. Follows the same pattern used in publish-cli-docs.yml for automated documentation updates.

<issue_description></issue_description>

<agent_instructions>Update eng/pipelines/build-notice.yml to do some new things:

1. Update the NOTICE.txt file at the root of the repo with the newly generated NOTICE.txt file. Keep the file name casing.
2. Use logic like the following in the build-notice.yml to create a PR:

            - template: /eng/common/pipelines/templates/steps/create-pull-request.yml
              parameters:
                PushArgs: -f
                PRBranchName: update-notice-txt
                CommitMsg: Update NOTICE.txt
                PRTitle: Update NOTICE.txt

When the code is ready to review, mention me directly in a PR comment to come and verify the work. </agent_instructions>
