DrupalPod Browser Extension: Update to Manifest V3

Pull request is ready for review: https://github.com/shaal/drupalpod-browser-extension/pull/12. Tested on Chrome, Firefox, and Safari.

Thanks for working on this @darren - The authoritative code for Drupalpod is here, not on github. Please do your update as an MR here, thanks.

When you do it, please provide instructions on how to test your updated extension, and what it has done.

The pull request is on GitHub because I could not find the extension code here. Please point it out to me if I missed it.

All of the code from GitHub came over here, https://git.drupalcode.org/project/drupalpod

That's the code that runs on GitPod. It does not include the browser extension.

Oh, sorry, I didn't even know about the other repository, and didn't read carefully enough!

Please add testing instructions to your PR. It seems to have all the coderabbit nonsense but nothing to say what was done or how to test it.

Added testing instructions to the PR.

Thanks for your work on this. @shaal did a competing v3 update and it's deployed and is working.
