Description
This is a follow-up for #37559.

The PropertyInfo component cannot identify collection values with a union type value like array<string|int> at the moment. Currently, it's only possible to identify singular types (e.g. string or \A) or types that are nullable (e.g. string|null) for the collection value.

Example
Following types cannot be identified at the moment:

array<string|integer>
array<string|integer|null>
array<A|B>
array<A|B|C>

and so on..
