Subject: [PATCH] chore(release): add automated release workflow (#2)

* chore(release): add automated release workflow

Adds a workflow file which can be run to create a semantic
tag and immediately afterwards, create a release on GitHub.

Any collaborator with write access should be able to
trigger the workflow.

This commit also adds another workflow file, which leaves a
comment after a PR has been merged. The comment reminds to
trigger the aforementioned release workflow.

* chore: delete pr commenter

* chore: fix naming and specify defaults

* chore: skip release if release exists

* chore: release if tag is provided to the step properly

* chore: default bump is patch if no input tag

* chore: attach files to GitHub release

Per feedback: https://github.com/canonical/rocks-toolbox/pull/2#discussion_r1255686934

* chore: remove . directory from the archive

* chore: make sure to pass down the archive file name
