Add GitHub Actions to automate updating stubs

[swissspidy]

It would be nice if this was done in a weekly or so GitHub action that could perhaps also be run manually if needed.

That would make maintenance a breeze.

I might take a stab at it if I find some spare time and if this is something you're interested in.

:) Excuse me! I like releasing stubs.

This is how it is done nowadays.

• watch #announcements on WordPress Slack
• wait for Packagist to refresh its cache
• run ./release-latest-versions.sh
• push to GitHub
• check TravisCI

No.

Even AI wouldn't help.

Crisis!
