incorrect installation instructions for 3rd-party flakes of type 'git'

[raboof]

One of the 3rd-party flakes is git+https://github.com/raboof/dmake?ref=nix

The search result page at https://search.nixos.org/flakes?query=dmake however suggests installing https://github.com/raboof/dmake#default, which is not the right url.

This would likely be fixed if we switched to full flake syntax instead of the 'custom'(?) toml, as suggested in #1145 - but a more targeted fix could also be possible.

Yes

instead of the 'custom'(?) toml

Yes, the current manual.toml file is custom and non-standard (at least until NixOS/rfcs#193 is accepted)
