`PartialDeep` make `Date` internal structure partial

[caiorhian]

I've noticed that when you apply PartialDeep to something containing Date it makes the Date internal structure partial, which causes some errors when combining it with zod validations for instance.

Should it skip internal JS classes like Date while making something partially deep?

I've found https://github.com/sindresorhus/type-fest/pull/342, but I still see the issue on version v4.4.0, might be a regression?

I think that one only handled Date as the input object, not as a deep value.

Can you provide your test cases? I seem can't reproduce that.
