add rapids-dependency-file-generator pre-commit hook (#531)

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.
