Nixpkgs backports

[purcell]

There seem to have been some changes made to the poetry2nix overrides in nixpkgs over the last 3 months, and I guess we want them here too, in order to have this repo be the ultimate source of truth?

NixOS/nixpkgs@b9b3be8e099f
NixOS/nixpkgs@6b63908
NixOS/nixpkgs@253a291

Alright, so the wheel change from downstream fails the tests here. Is this PR misguided? What's the plan for getting updates from here into nixpkgs now? It seems the release numbering scheme changed in June and there haven't been any syncs into nixpkgs from here since then.

See also #1291; there was a corresponding update to python3.pkgs.wheel, so we need to update our nixpkgs commit at the same time.

Oh, I see, you mean the pinned version used in CI here. Makes sense. I'll add a commit here which bumps the flake deps, but I'll leave it to @adisbladis / @cpcloud to suggest how best to coordinate all this.

[purcell]

Hmm, if that was indeed the suggestion, it didn't fix the build issue. I'll back out that commit to minimise the noise.

[andersk]

Well yeah, there seem to be other issues with bumping the nixpkgs commit, which is why I linked #1291.

[cpcloud]

Closing this out in favor of #1329.
