PR Summary

• New Feature to Label Internal Issues
  A new file has been added that allows the system to automatically tag certain issues with the label "Internal". This will help segregate internal issues from the rest, enabling faster identification and resolution.

• Script to Remove Certain Labels
  A function has been introduced that can remove specific labels like 'run-visual-tests', 'pause-pages', and 'WTD' from an issue when required. This will declutter the system and keep the focus on only the relevant information.

• Enhancements to label-pull-requests Workflow
  Modifications have been made to the existing workflow. The workflow now includes a step that uses an included script to add the "Internal" label to any pull requests starting the title with "Internal:".

• Ability to Remove Labels on PR Closure
  Further improvements to the workflow also include a script that can remove labels when the pull requests are closed. The system will automatically discard any unnecessary labels, ensuring the interface remains clean and organized.
