Fix audit revision query for enum column mapping

[X-Coder264]

Subject

I am targeting this branch, because it's a bug fix.

After doctrine/orm#10088 we get an enum object back in the DEL revision saveRevisionEntityData code path instead of an integer or string value which then blows up on the $conn->executeStatement() call with the following exception:

Error: Object of class Sonata\EntityAuditBundle\Tests\Fixtures\Issue\Status could not be converted to string

vendor/doctrine/dbal/src/Driver/PDO/Statement.php:56

Changelog

### Fixed
- Audit query for Doctrine ORM >= 2.14.1 for entities with enumType column mapping

Thanks for the fix, do you have time to take a look at the ci errors ?
You'll need to

• Solve some linters errors
• Solve some "possiblyNull" static analysis error by adding static::assertNotNull($foo).
• Skip the test for PHP version which doesn't support ENUM

Even though the test I've added is marked as requiring PHP 8.1 to run, the PHP 7.4 and PHP 8.0 pipelines are still failing as the entity with the enum mapping class metadata is still being registered (so it blows up in Doctrine/ORM/Mapping/ClassMetadataFactory). Does anybody have a suggestion how we can solve this?
