Merge branch 'rsc-enable-nixfmt-hook'

Making this change was unexpectedly annoying (yak saving 🙁). All I
wanted to do was add a flake.nix file to another private Git repo.
Before I could add the flake.nix file, I had to open a pull request for
nixfmt [1] so that I could create four different commits in this repo so
that I could make sure that Nix files get styled properly so that I can
START creating the flake.nix file in that other repo. Plus, there will
probably be more problems that I encounter while creating the flake.nix
file, and I’ll end up having to make more changes to this repo.

In other words, this is just the beginning of the yak shaving.
