Feature request: make `git_latest_tag` work with CalVer release schemes

A few months ago I noticed that git_latest_tag does not work as expected for CalVer releases. Seems to work just for semantic versions.

@epassaro thank you for raising this. I have converted it into a feature request.

The two workarounds I found months ago were:

1. Update git on CircleCI to use git describe --tags --abbrev=0
2. Get the latest tag from the GitHub API

Is any of these two options good enough? I think the second probably not.
