unstableGitUpdater: Allow using stable versions

It is important to keep the version as parsed by `builtins.parseDrvName`
monotonic for packages that often switch between stable and unstable versions,
for nix-env to be able to update them reliably.

Let’s optionally use the version format described by RFC 107:
https://github.com/NixOS/rfcs/pull/107
The downside is that it requires fetching
more commits to be able to determine the latest tag.
