Add `communicate-on-pull-request-released` GitHub Action

[mollyIV]

Description

The action will:

• add a comment to the pull request about including the changes in a release

  Congratulations! 🎉 This was released as part of fastlane x.y.z 🚀

• add status: released label to the pull request and remove status: included-in-next-release label from it if existing
• add a comment to the referenced issue that the pull request has been released

  The pull request #xxxxx that closed this issue was merged and released as part of fastlane x.y.z 🚀
  Please let us know if the functionality works as expected as a reply here. If it does not, please open a new issue. Thanks!

Please note that this is just an action implementation. It does not take any effect itself. A new workflow which uses the action will be created.
