chore(ci): Upload halconfigs to GCS on Tag push (#1174)

Previous release tools would publish basic halconfig profiles to GCS
bucket: [https://console.cloud.google.com/storage/browser/halconfig/`<service>`/`<version>`/*](https://console.cloud.google.com/storage/browser/halconfig/%60%3Cservice%3E%60/%60%3Cversion%3E%60/*)

Where `<service>` might be `rosco` and `<version>` is our git tag, eg: `v1.2.3`.

Halyard downloads these profiles during `hal deploy apply`.
As the profiles are deprecated it would be ideal to remove from Halyard
but it may break users workflows.

For now we can upload the files as part of our regular service 'release'
flow (git tag <version> && git push) using GHA.
