[master] Update git2 version

[pietroalbini]

This PR bumps the version of the git2 and libgit2-sys crates to pull in fixes for GHSA-m4ch-rfv5-x5g3.

This does not fix any security vulnerability: Cargo is already protected thanks to the fixes we implemented as part of CVE-2022-46176. The only purpose of this PR is to avoid dependency scanners from flagging vulnerabilities.
