Fernando Rodrigues 2e76f1b474 shell.nix: include gh in the default shell
GitHub's CLI is now used by nixpkgs-review to fetch Nixpkgs evaluation
results from GitHub Actions. Including it in the default shell will
allow all contributors to easily log-in to GitHub when nixpkgs-review
tries to fetch evaluation results.

# A shell to get tooling for Nixpkgs development
#
# Note: We intentionally don't use Flakes here,
# because every time you change any file and do another `nix develop`,
# it would create another copy of the entire ~500MB tree in the store.
# See https://github.com/NixOS/nix/pull/6530 for the future
#
# Note: We use a pinned Nixpkgs so that the tools are readily available even
# when making changes that would otherwise require a new build of those tools.
# If you'd like to test out changes to the tools themselves, you can pass
#
# nix-shell --arg nixpkgs ./.
