👷 Sign release commits with Jack's token

We have a requirement that all repository commits be signed. This
means that automations should also sign commits.

We are setting up commit signing in the repository, but there is no
way (that I know of) to currently pass that git config into the
container in which covector is running its action.

This checks which action covector ran and then if it is `version`,
re-commits HEAD which is configured to use Jack's credentials and
config.
