fix issue with nested vector fields and python 3.13 issubclass changes

[sethbuff]

The main purpose of this PR is to support python 3.13.

There is a change to issubclass where if you feed in a type like list[float], it will raise a type error because it does not validate that the inner types are floats and so it now raises an error instead of possibly returning a false positive.

In troubleshooting this, we also came across this PR: #674 from @huwaizatahir2, making this change (and updating the field to be list[float] instead of list[list[float]] also resolved the issue we were facing.

For backwards compatibility, we still allow list[list[float]] but we wanted to also support what is probably the correct way of defining vector fields which is list[float].

We also kept running into the flaky test from tests/test_hash_model.py::test_pagination_queries so we went ahead and pulled in the fix from this PR: #694

This PR should now make it possible to use redis-om with python 3.13 as well as fix the issues associated with the other 2 PRs tagged above.

This look great! 👍 Let's keep an eye on that _is_numeric_type function. If it ends up used elsewhere, we could consider throwing it in utils.py and use a for loop as a performance optimization.

Good call, we definitely needed to test against 3.13

That makes more sense, I'll go ahead and throw it in there now to set a precedence for functions like that going forward.
