Cannot findBy with a string on a DateTime field since 2.20.7

Bug Report

Q	A
Version	2.20.7 (still happening in 2.20.9)
Previous Version if the bug is a regression	2.20.6

Summary

Hello !

Since the 2.20.7 update, it looks like we cannot do a "findBy" on a Doctrine\DBAL\Types\Types\Types::TIME_IMMUTABLE (or DATE_MUTABLE) field with strings anymore

Replacing the strings with \DateTimeImmutable does the trick

Current behavior

Create an entity with

	#[ORM\Column(type: Types::DATE_IMMUTABLE)]
	private ?\DateTimeImmutable $date = null;

Use it like this

$this->em->getRepository(MyEntity::class)->findBy(['date' => '2025-02-04']);

Could not convert PHP value '2025-02-04' to type date_immutable. Expected one of the following types: null, DateTimeImmutable

 trace: {
        /vendor/doctrine/dbal/src/Types/ConversionException.php:78 { …}
        /vendor/doctrine/dbal/src/Types/DateImmutableType.php:41 { …}
        /vendor/doctrine/dbal/src/Connection.php:1887 { …}

        /vendor/doctrine/orm/src/Persisters/Entity/BasicEntityPersister.php:995 { …}
        /vendor/doctrine/orm/src/EntityRepository.php:224 { …}

Expected behavior

I should get an array with every MyEntity with the date of 2025-02-04

The culprit seems to be https://github.com/doctrine/orm/pull/11895/files#diff-3ca09663ec045c8f6549f5960c6cf11c38a839c46eb6efb2151c0c00498e3045.

Possibly relates to #12245.
