At the top of maintainers.nix it says that:
> Entries here are expected to be follow the same format as described in [1]
Typo aside, [1] links to NixOS' maintainer-list.nix file off a 5 year
old commit, which contains outdated information on which maintainer
fields are required. Notably, `github` and `githubId` have since become
mandatory, while `email` was moved to the list of optional fields.
This updates the link to point to the current version of the file.
