Context

The ai-ml-pipeline-testing repo needs a linter. Since the repository is primarily written in bash and python, for now we need a pre-commit that will lint/format both the python and bash files. 

Additionally, having a github action that checks linting and formatting would be great as well.

What should the implementer watch out for? What are the risks?
