Add additional parameters and move behavior into action.yml

[pwtyler]

• Moves behavior into action.yml, removing shell script
• Drops lint CI step.
• Drops the expectation to pass gh-token (I think this should just work)
• adds tag as output
• Don't install autotag if already found

New input params

• push-tag (bool): whether to push the tag or not
• push-major-version-branch (bool): whether to push to a major version (i.e. v1) branch
• v-prefix (bool): whether to prefix the tag with v or not
• create-release (bool): whether or not to create a release. Should allow "draft" in a future release.
• workdir: directory with the code to tag

The input params have been set such that the default behavior matches current behavior— we should determine which, if any, should be flipped as part of released a v1.

TODO

• Move longer sections back into shell scripts
• Docs

Tested releasing with https://github.com/pwtyler/autotag-sandbox/blob/main/.github/workflows/autotag.yml and successful action steps can be found there.

Realized I still need to update docs...

Moves behavior into action.yml, removing shell script

Okay, but why? Literally 6 months ago you were telling me we should put shell code into shell scripts rather than GH actions. I'm not opposed but not sure it's necessary? (And if we can shellcheck the shell code, and run parameterized functions in a single .sh I would prefer that over not being able to lint the shell code.

So Greg and I discussed this a bit last week because I was torn as well— the primary reason was because I was adding the conditionals to each step, and if I wanted all of that in a shell script, I'd be exporting values like ${{ inputs.push-tag == 'true' }} to variables or args to the shell script.

That said, as this action.yml file has come together, I could move anything > 3 lines or so into small shell scripts (e.g. the tag step and the push step each their own script).
