Barebones workflow to trigger pre-commit github action

[jdye64]

Description

Barebones Github Action configuration to install and run pre-commit on the nv-ingest codebase

Developers will need to now make sure that pre-commit is installed in their development environment. This is included in the util-requirements.txt file now or you can simply run pip install pre-commit.

Then you must install the pre-commit hooks with pre-commit install

If you find yourself working on a PR prior to this commit that does not have pre-commit you can skip the pre-commit checks and commit time by running git commit -m "commit without checking" --no-verify

This checks for

• Trailing whitespaces
• Fixes end of lines to include a single blank line
• check that no files larger than 1,500kb are committed. Maybe we adjust later?
• check that python files are valid
• format and lint with black to PEP8 standard

Checklist
