add rapids-dependency-file-generator pre-commit hook

[jameslamb]

Contributes to rapidsai/shared-workflows#46.

Proposes adding a pre-commit hook to run rapids-dependency-file-generator.

With that change, local pre-commit and CI will raise an error if changes to dependencies.yaml cause some error from rapids-dependency-file-generator.

If this project checks any files modified by that tool into source control in the future, it'd also raise an error if any of those files change.

This is a bit cheaper way to find out about things like typos, misaligning spacing, etc. than waiting for CI to report it. It's very fast, shouldn't be noticeable in day-to-day development.

How I tested this

Changed an output: conda to output: condafile (not a valid output type) in dependencies.yaml.

Ran pre-commit run --all-files.

Observed the expected failure.

Reverted that change, ran pre-commit run --all-files again, saw everything pass.
