Specify custom injections in .config/helix

[414owen]

I have helix 22.08 (ee94031f) installed from nixpkgs.

Helix doesn't seem to load injections.scm from ~/.config/helix/runtime/queries/haskell, or anywhere similar (I ran strace to see where it looks).

It would be great to be able to specify custom injections, for example, I'd like to be able to highlight the sql in my haskell, and the bash in my nix.

I guess the more general enhancement would be load locally specified runtime files, and merge them with the global versions?

It currently reads queries from a single runtime path, but I think we should support multiple: it should look into HELIX_RUNTIME, as well as ~/.config/helix/runtime for files.

Yeah this would be more sane behavior. I think this falls under #3346 so I'll close in favor of that one
