increase parallelism in nightly builds

[jameslamb]

Description

Contributes to rapidsai/build-planning#136

For nightly builds, some wheel-build-{project} jobs currently wait to start until some other wheel-publish-{dependency} jobs complete. This is unnecessary... wheel-build-{dependency} jobs will upload packages to S3, which is where wheel-build-{project} jobs will download them from.

This proposes changing that such that all nightly wheel-build-* jobs depend only other wheel-build-* jobs. This should decrease the end-to-end time it takes for all wheels to be built and published on nightly / branch builds.

Also updates pre-commit config to the latest rapids-dependency-file-generator version.
