[FEATURE] Experiment with Mypy pre-commit ci

[benjaminwp18]

We run Mypy linting with our ROS linter Github action right now. The test_mypy.py files in each ROS package test folder configure it. That means our Mypy version is tied to our ROS/Ubuntu version, so we can't use features like the new Python generics notation (see below).

rov-25/pyproject.toml

Lines 26 to 27 in f8f9312

	"UP046" # Ruff pre-commit wants updated generics notation but ROS2's Mypy tests don't support it
	# Ignore Ruff for now, change this when we move to next Ubuntu LTS or pre-commit Mpypy

Consider switching Mypy to pre-commit hooks as well to give us more versioning freedom: https://github.com/pre-commit/mirrors-mypy.
