Nixpkgs: gotools package no longer installing gopls

[roman]

Describe the bug

The gotools package was relying on the fact that there was a cmd/gopls directory in go's tools repo. Unfortunately, this directory was removed on commit 8647d4c87977ec65bfce87fe963652c71cd2e0db

Not sure when the gopls binary stopped being shipped in nixpkgs.

To Reproduce
Steps to reproduce the behavior:

1. install latest version of the gotools
2. Search the bin directory of the output from the derivation and assert the gopls command is no longer there
3. n/a

Expected behavior
The gopls command should be available, it's a crucial binary, as it is used for lsp support

gopls is now available in gopls package. This was changed in https://github.com/NixOS/nixpkgs/pull/85868

Uhm, silly me, didn't check there was an independent gopls package now.

Would you say it is a good idea to update the referenced comment in this ticket? I can volunteer to update the comment.
