switch to `nushell` and drop gitpod

Add nushell to devShells.default

I still need to fixup the README regeneration.

This also replaces nix-build-uncached with nix-eval-jobs.

[Artturin]

https://github.com/nix-community/nixpkgs-wayland#development-guide should also be updated

[colemickens]

the readme is annoying. using take until, skip until with the comment delimiters seemed promising but it drops newlines.

If I use ripgrep the same way, somehow it mangles a bunch of the text even with | save --raw ...

readme generation in python https://github.com/nix-community/nixpkgs-wayland/pull/380 if preferred

[colemickens]

It wound up not being that bad, I think I'd made a silly mistake at first. I prefer this over the python version (dependencies, my general aversion to python, there's only one small sin being committed here using ripgrep, etc).

[colemickens]

There's also some other small cleanups to the internals of the flake, reflecting some changes I'd made in my own config too.

Notably, I eliminated waylandPkgs from the overlay, and packages now invokes the overlay directly to produce its package set instead of using waylandPkgs. It also no longer includes the "linkFarmDrv" default package, because it makes it easier to let nix-eval-jobs be efficient.

[colemickens]

alright, I'm actually pretty happy with this.
