Feature: Built in artefact collection

[Bertg]

Love the action, it's pretty great. We've started using the example given in the docs (https://github.com/jwalton/gh-docker-logs#upload-tarball-as-artifact) to collect, tar and upload the logs as an artefact.

I guess this could be done using https://github.com/actions/toolkit/tree/main/packages/artifact ?

Would this be something you'd consider?

I would definitely accept a PR.
