fix: 👷 explicitly checkout newest version to publish (#107)

# Description

Currently, the publish step checks out the current *commit*, which isn't
the same as the current version (the previous step creates a release
commit with version bumping). This PR fixes that to explicitly checkout
the newest version (tag).

No review needed.
