TYP: NumericIndex._can_hold_na

[twoertwein]

Index._can_hold_na: bool
NumericIndex._can_hold_na: property-like (cache_readonly)

bool is not a property-like object.

pandas/core/indexes/numeric.py:103: error: Signature of "_can_hold_na" incompatible with supertype "Index" [override]

so do we need a "type: ignore" here?

Probably yes, or the parent-class should also use cache_readonly.

I opened this and the other 3(?) issues because I wasn't familiar enough with these code portions. Looking backward, all of them can probably use a "type: ignore" at least initially.

Should have been closed as part of #43828
