Chore/add automated release or update of major GHA version

[jimid27]

• Resolves: https://linear.app/prefect/issue/PLA-706/automate-actions-prefect-deploy-release-updates
• Goal of this PR is to automatically repoint or create a new major version of the github action when a semver release is created.
• In the event that the semver release is just a minor or patch bump of the action, we will repoint the major version i.e v1 to point to that semver sha
• In the event that a new major release occurs i.e 5.0.0, this action will automatically create a release for the major version i.e v5

we may want to add the notify-on-failure workflow here so that we are alerted if something goes wrong with this release. Similarly, we may want to add a release script like we have in our internal repos to make creating the release/tag consistent & easy

I think this can be ref'd by $GITHUB_TOKEN but i could be wrong

https://github.com/elgohr/Github-Release-Action?tab=readme-ov-file#github-release-action I was going off of this referenced by the github actions docs and I think it works since I tested a major bump in my own repo but if theres a better way I'm def down to change!

[jamiezieziula]

what does this mean?

[jimid27]

Means we don't want to run this action when a major version (i.e v5) is tagged and released

[jamiezieziula]

what is the else statement doing then if not running on a major release?
