Trigger Pipelines For Copilot Pr

Post the following two comments to the PR specified by the user ($ARGUMENTS), in the microsoft/FluidFramework repository on GitHub.

They need to be posted separately because otherwise it gets too long and

fails to trigger correctly.

First comment:

/azp run Build - protocol-definitions,Build - test-tools,server-gitrest,server-gitssh,server-historian,server-routerlicious,Build - client packages,repo-policy-check

Second comment:

/azp run Build - api-markdown-documenter,Build - benchmark-tool,Build - build-common,Build - build-tools,Build - common-utils,Build - eslint-config-fluid,Build - eslint-plugin-fluid

Posting those comments will trigger all our pipelines, which is necessary for PRs that are created by Copilot.

To post the comments first check if the GitHub CLI is available,

and if so use MSYS_NO_PATHCONV=1 gh pr comment <PULL_REQUEST_NUMBER> --repo microsoft/FluidFramework --body "<COMMENT_TEXT>".

Note: MSYS_NO_PATHCONV=1 is required on Windows (Git Bash) to prevent /azp from being expanded to C:/Program Files/Git/azp.

If gh is not available but $GITHUB_TOKEN is, you can try the GitHub REST API directly, e.g.:

curl -L \
  -X POST \
  -H "Accept: application/vnd.github+json" \
  -H "Authorization: Bearer $GITHUB_TOKEN" \
  -H "X-GitHub-Api-Version: 2022-11-28" \
  https://api.github.com/repos/microsoft/FluidFramework/issues/PULL_REQUEST_NUMBER/comments \
  -d '{"body":"<COMMENT_TEXT>"}'

If neither is available, don't do anything and tell the user you can't complete the request and why.
