Bump action github

First bump, from v5 to v7, stop using nock and just jest instead.

Thanks @VincentLanglet. This works, but it removes the confidence I have when upgrading @actions/github as the HTTP client is now mocked and the signature may have changed.

I think the msw path is better as we can assert actual HTTP requests
