Enum Array Support with `simple_array` Type

It seems that enum arrays are not supported, or am I doing something wrong?

```
/**
* @var FieldType[]
*
* @ORM\Column(type="simple_array", enumType="Demo\FieldType")
*/
private array $supportedFields;
```

I can't use `grabFromRepository()` or `seeInRepository()` as it seems like the module doesn't internally handle the conversion to a comma-delimited string properly. I'm not sure if this issue includes `haveInRepository()` as well since have not tested it.

```
$result = $this->tester->grabEntityFromRepository(Demo::class, [
...
'supportedFields' => [FieldType.Field1, FieldType.Field2, ...] // <-- problematic
]);
```

Crashes with a SyntaxErrorException:

```
Doctrine\DBAL\Exception\SyntaxErrorException : An exception occurred while executing a query: SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near ","
LINE 1: ...$1 AND d0_.name = $2 AND d0_.supported_fields = $3, $4, $5, ...
^
```

Start by locating grabEntityFromRepository(), grabFromRepository(), seeInRepository(), and haveInRepository() in the Doctrine module, then inspect how repository criteria are passed to Doctrine for simple_array fields. Reproduce the failure with the shown enum-array mapping and PostgreSQL setup. Done means the affected helpers handle the array value without generating invalid SQL, with regression coverage for the supported methods.
