Add @typing.override to functions

Feature Request / Improvement

For example, Catalog functions and FileIO functions

Only for Python 3.12 but that's ok since we run 3.12 in CI

Would you recommend something like this:

from typing import TYPE_CHECKING

if TYPE_CHECKING and sys.version_info >= (3, 12):
    from typing import override
else:
    # Define a no-op decorator when TYPE_CHECKING is False
    def override(func):
        return func

If so, would you recommend putting this in some kind of utility .py file? Seems like it would get used an awful lot across the codebase

@cosmastech I dont think we need to do the override. For Python versions less than 3.12, I think this will just be a no-op
