remove me as maintainer

I don't use these tools anymore, so it makes sense I shouldn't have an
opinion on PRs that change/update them. I know it's always unfortunate
losing a reviewer, but I'm not very active anymore anyway,
unfortunately. Apologies.

From now on, I'm trying not to add too many packages into nixpkgs, since
flakes are available. I guess when I first started using Nix I got
overexcited by how easy it was to contribute, so I added things for the
sake of adding things (not because I necessarily used them).
