GitHub Action: use latest version (unless version is specified)

[MPV]

...to lower the maintenance need for this action (keeping it updated when there's newer versions of Octopilot released).

TODO:

• Manually verify that both scenarios (with & without version) works as intended.

@MPV thanks for your PR. Do you need anything to finish it?

[MPV]

@vbehar This is now ready.
I have tested it over here:

• https://github.com/MPV/octopilot/actions/runs/6558520889
• Create .github/workflows/test.yml (for testing GitHub Action) MPV/octopilot#1

It works on ubuntu-latest (i.e. not yet on macos-latest / darwin), but that can be improved in a later PR/change imho.

[MPV]

Rebased from master. Feel free to squash this into master (if/as you see fit).
Let me know if you need me to squash it first instead.

[MPV]

I haven't added any workflow testing the action, but I suppose you could do something like what I did:

• https://github.com/MPV/octopilot/pull/1/files
• https://github.com/MPV/octopilot/blob/patch-2-test/.github/workflows/test.yml

...maybe with something like this to avoid it running on any PRs when not needed:

[...]
on:
  pull_request:
    paths:
    - action.yml

...as per:

• https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#onpushpull_requestpull_request_targetpathspaths-ignore

...but not a must-have in this PR, so I'll leave it for later.

thanks! Yes, ideally if you can squash & sign your commit, then I'll be able to merge it

[MPV]

@vbehar squashed and signed now, feel free to proceed.

@vbehar squashed and signed now, feel free to proceed.

sorry, I meant GPG-signed, not signed-off. As explained in https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits (it's a requirement we have in this repo...)

[MPV]

@vbehar How about now? The commit says Verified when I look at it — hope I got it right. 😊

[vbehar]

perfect, thanks a lot!
