[CI] New workflow for updating pre-commit hooks

[ferbetanzo]

Since dependabot does not check dependencies in pre-commit config files, we need a workflow that runs pre-commit autoupdate and checks if any hook versions are udpated, if so, the workflow should create a PR.

Example: https://github.com/browniebroke/pre-commit-autoupdate-action

Looks like that action does what we want?
