2.17 broke bigint validations

[gabplch]

BC Break Report

Q	A
BC Break	yes
Version	2.17.*

Summary

Running doctrine:schema:validate

I suspect #10946

Current behavior

[FAIL] The entity-class App\Entity\Foo mapping is invalid:
 * The field 'App\Entity\Foo#bar' has the property type 'int' that differs from the metadata field type 'string' returned by the 'bigint' DBAL type.

How to reproduce

class Foo
{
    #[ORM\Column(type: Types::BIGINT)]
    protected int $bar = 1;
}

Expected behavior

No errors
