jsonschema: {relative,absolute}_path can hold ints

[DMRobertson]

In matrix-org/synapse#12901 I noticed an problem with the changes to the jsonschema stubs in #7950.

This change remedies that by teaching mypy that paths, relative paths and absolute paths on Error objects can hold strings, ints, or a mixture of the two. For evidence that this is the case, see e.g. https://github.com/python-jsonschema/jsonschema/blob/2e2832463e8de7977217d377ca0553c10f6fb48c/jsonschema/tests/test_exceptions.py#L246-L247 or the test case I provided in #7950 (comment).

@sirosen, does this change make sense to you? :)

Yes, this change is definitely an improvement -- the OP's comment/example on the earlier PR is accurate, and I'm sorry I didn't catch this earlier.

I'm looking now to see if there are other [str] containers which should be [str | int]. But I'm not sure we want to block this while I do that?

I'll merge for now; further fixes can be made in further PRs if necessary.

Thanks for the fix, and thanks @sirosen for confirming!
