Subject: [PATCH] flake/dev: pin flake-compat to PR fixing shallow repo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pin flake-compat to https://github.com/edolstra/flake-compat/pull/75
which fixes https://github.com/edolstra/flake-compat/issues/74

If the flake is a shallow git repo, such as when fetched in CI,
flake-compat was failing to run in nix-instantiate.

Flake lock file updates:

• Updated input 'flake-compat':
