Devbox support

[aaomidi]

Is your feature request related to a problem? Please describe.
Inability to use my existing devbox.lock file with this rule is a bit frustrating, but its not necessarily this tools job :P.

Describe the solution you'd like
I already use devbox for dependency management for the tools I use. I would like if I can reuse the same devbox.lock file that I use for my local dev environment, inside Bazel.

Describe alternatives you've considered
Just using rules_nixpkgs

Additional context

I think that should actually not be too complicated. You could create a repository rule which reads the lock file (it's just JSON) and extracts the resolved value (which looks like github:NixOS/nixpkgs/5775c2583f1801df7b790bf7f7d710a19bac66f4#ripgrep) of each tool you want to import.

Then, split at the # and generate a call to nixpkgs_git_repository for the first part, a nixpkgs_package (or toolchain rule) for the second.

Given that it needs to invoke other repository rules it might even lend itself better to a module extension.
You can take a look at nix_pkg and nix_repo for reference.
