feat(gs/home): Add config for email notifications r/1301

This uses the notifymuch package pulled from
https://github.com/NixOS/nixpkgs/pull/92797 right now, but eventually I
would like to pull from a vendored version since there are some changes
I would like to make to how the notifications are rendered and it looks
like upstream is unmaintained.
