fix(git): dont fetch tags by default

Change Cargo to pass [`--no-tags`] Git CLI option by default.
This aligns with how libgit2 works in Cargo.

Based on the Git official doc,
the flag has been there since at least 2.0.5

[`--no-tags`]: https://git-scm.com/docs/git-fetch/2.0.5#Documentation/git-fetch.txt---no-tags
