Breaking change using genId property configuration

[GSadee]

API Platform version(s) affected: 4.1.17

Description
After the PR, the behaviour of using genId has been changed.

How to reproduce
In Sylius, we set genId="false" on a single property (here). After the changes introduced by this PR, all properties nested inside it now inherit genId="false" as well, which causes the returned IRI to be using a different strategy than before. This if statement is now ommitted. Even though I explicitly declare genId="true" for those child properties in a separate property configuration, that override is ignored.

Possible Solution
Be able to explicitly define the genId for given property.

I don't understand:

If properties inherited from that they'd all not have an iri as genId would be false and you'd not get any IRI right?
