Fix zero exponent for ints

[Molkree]

It is typed as int instead of Any after this PR.

Followup to #6325 (comment)

Could you add the new overload to the pow definitions at lines 1349 and 1383, as well?

Mhmmm, of course, missed those.

Overloads there require # type: ignore[misc] just like _PositiveInteger/_NegativeInteger overloads. Without it I'm getting errors like this:

Overloaded function signatures 3 and 10 overlap with incompatible return types

Yeah, mypy gets all panicky about this kind of thing, but infers the types just fine anyway ¯\_(ツ)_/¯
