Update GitHub actions now that the repo is getting more attention.

This will change a lot as I learn more about GitHub Actions.
If you'd like to lend a hand please comment.

TODO:

• Update version to match protobuf versions
• Create an Action to update protobufs automatically and release a new version
  • BONUS: Update protobuf's Actions to fire off this Action or subscribe to protobuf releases somehow
• Don't allow updates to .github files to update Actions and run without approval (SECURITY)
• Ensure the version is bumped when merging to master
• Only publish to NPM and JSR when a release is created
