Add __cuda dependency to lightgbm

[cbourjau]

Checklist

• Used a static YAML file for the patch if possible (instructions).
• Only wrote code directly into generate_patch_json.py if absolutely necessary.
• Ran pre-commit run -a and ensured all files pass the linting checks.
• Ran python show_diff.py and posted the output as part of the PR.
• Modifications won't affect packages built in the future.

Further context

#789 Added __cuda as a dependency for lightgbm packages depending on cudatoolkit. However, not all cuda builds have that dependency and were thus missed.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

Could you merge this with the above one and simply omit the (not_)has_depends?

After merging the two yaml sections, show_diffs.py yields the same output as before.
