Context: Follow up from sync with @itsjustkevin today. Tag and ping the actor of workflow, when the cherry pick pull request is successfully created. 1. actor of workflow will be the username of the user that triggered the initial workflow run. i.e., whoever labels the PR. This person might not necessarily be the author of the cherry pick PR. 2. PR number of newly created cherry pick PR is parsed from the output of "gh pr create" as a multi line string. Tested: on cp success: https://github.com/flutter/flutter/pull/142674 pings the actor of workflow (not the pr author). on cp failure: [example workflow](https://github.com/XilaiZhang/miscellaneous-side-project/actions/runs/7734400373/job/21088324523) leaves a msg on the original PR.
