Add git commit hash to CLI output

[hu55a1n1]

Summary

Print the git commit hash in the description. This makes it easier to identify the exact source that was used to create the CLI binary and will help us in debugging user/dev issues in the future.

Acceptance Criteria

• The git commit hash must appear on stderr for all CLI commands.

@hu55a1n1 do we prefer the long or the short hash?

[hu55a1n1]

This is what I had in mind -> <pkg-version>+<git-branch>-<git commit hash (short)>, e.g. 0.1.0+hot_fix_branch-760270a8-dirty. Here's the PR where we implemented this for hermes -> informalsystems/hermes#1101
Also would be nice to display just the version if quartz was installed using cargo install (i.e. the public release).
