Add pre-commit hook for rye lock

[Jeffrey-Lim]

Add a pre-commit hook that simply runs rye lock to ensure that requirements.lock is up to date with pyproject.toml. This is supposed to act similarly to the poetry-lock pre-commit hook.

I've tried to create a hook myself, but there is no straightforward way. You would expect that you could add a .pre-commit-hooks.yaml file like this:

- id: rye-lock
  name: rye-lock
  description: Run rye lock to update lock files
  entry: rye lock
  language: rust
  pass_filenames: false
  files: ^(.*/)?(requirements(-dev)?\.lock|pyproject\.toml)$

Unfortunately, pre-commit internally runs cargo install --bins --path ., which results in the error error: found a virtual manifest at <path> instead of a package manifest. Running cargo install --bins --path ./rye instead does work, but the pre-commit maintainer is against making --path configurable.

I tried to make a hook that relies on the host installation of rye instead like this:

- id: rye-lock
  name: rye-lock
  description: Run rye lock to update lock files
  entry: rye.exe lock
  language: system
  pass_filenames: false
  files: ^(.*/)?(requirements(-dev)?\.lock|pyproject\.toml)$

This works, but only on Windows, as you need to call rye.exe instead of just rye, so this hook is now platform-dependent.

You could also create a docker file and make use that in a docker pre-commit hook, but I don't think that is a good solution as you would need to install docker on your host machine.

Anyway, I hope that my findings will be a useful starting point for whoever wants to pick up on this.
