Need a .pre-commit-config.yaml to meet Contributing Guidelines recommendation

In submitting a PR, since this is my first, the act of reviewing the diff on GitHub suggests I check out the commit guidelines (https://github.com/bazel-contrib/.github/blob/c9d6d1893b10a8d68584a6ba52c3dd35506486d0/CONTRIBUTING.md). This seems to be a cross-org guideline simply recommending a basic `pre-commit install`.

Without the `--allow-missing`, this would require a `.pre-commit-config.yaml` to be checked-in at the workspace directory. I don't see one in the directory.

We likely need to add one: copying `https://github.com/bazel-contrib/rules_cuda/blob/main/.pre-commit-config.yaml` may suffice. Other repos in `bazel-contrib` seem to lack this config file.

Granted, the error appears because I didn't see a .pre-commit-config.yaml, so didn't install. Having run the command, I then run a `pre-commit run -a`, ant that produced the error:
```
Allans-MBP2019:rules_bazel_integration_test allanc$ pre-commit install
pre-commit installed at .git/hooks/pre-commit
Allans-MBP2019:rules_bazel_integration_test allanc$ pre-commit run -a
An error has occurred: InvalidConfigError:
=====> .pre-commit-config.yaml is not a file
Check the log at /Users/allanc/.cache/pre-commit/pre-commit.log
```

That log file follows.

Add the workspace-level .pre-commit-config.yaml, using bazel-contrib/rules_cuda/.pre-commit-config.yaml as the stated reference. Run pre-commit run -a from the repository root and confirm that the configuration is found and completes without the reported InvalidConfigError.
