core: BC Break on SearchFilter with date as input

API Platform version(s) affected: x.y.z

Description

If you use dates with the search filter, this was supported, it now triggers an exception. This is because previously the type was not always sent with the doctrine parameter, and doctrine was considering the date as string type (which is valid when you have a string like 2021-01-12 as input).

How to reproduce

If you have the following filter configured on an entity, it will break:

/**
 * ...
 * @ApiFilter(SearchFilter::class, properties={"something.id": "exact", "date": "exact"})
 */

Possible Solution

Add support for dates, which is a special case that is not that simple because it requires to manage date, datetime, datetime_immutable and so on.
