Description

Contributes to https://github.com/rapidsai/dependency-file-generator/issues/89.

--file_key has been deprecated in rapids-dependency-file-generator for a few months, and I'm looking to fully remove it.

This PR proposes:

• switching this project's uses from --file_key to --file-key
• updating the version of rapids-dependency-file-generator used in pre-commit to its latest release

By Submitting this PR I confirm:

• I am familiar with the Contributing Guidelines.
• When the PR is ready for review, new or existing tests cover these changes.
• When the PR is ready for review, the documentation is up to date with these changes.
