Backports r65249 to the 6.8 branch.

Switches GitHub Actions concurrency groups from github.head_ref (branch name only) to github.event.pull_request.number, so workflow runs from PRs opened from different forks with identical branch names no longer cancel each other. props-bot.yml uses github.event.pull_request.number || github.event.issue.number to also cover issue_comment events.

All files in this branch that use head_ref in a concurrency group were updated. Some of them (such as check-built-files.yml) do not exist in trunk.

• All changes will be lost when refreshing the page.
• A fresh instance is created each time the link below is clicked.
• Every time this pull request is updated, a new ZIP file containing all changes is created. If changes are not reflected in the Playground instance,
  it's possible that the most recent build failed, or has not completed. Check the list of workflow runs to be sure.

Checked against the 6.8 branch at 3b9ad0a: all 13 workflows whose concurrency group used github.head_ref now use github.event.pull_request.number, matching r65249, with the comment line updated to match. props-bot.yml uses the github.event.pull_request.number || github.event.issue.number form, same as trunk. No head_ref is left under .github/ and nothing else changed. CI: 215 passed, 22 skipped, 1 failed. The failed job is the SCRIPT_DEBUG end-to-end job: the site returned a 503 early in the run, then the media-upload test hit "Not logged in" on all three attempts. This change touches no test or app code, and the 6.8 branch's own end-to-end runs are green (latest push run 42147273253), so I read it as a test-environment failure. I re-ran the failed job and it passed.
