`make:entitiy`: Omit the meanwhile unnecessary `enumType`

This is the code that's now generated for an `enumType`:
```php
#[ORM\Column(enumType: Suit::class)]
private ?Suit $suit = null;
```
However, setting an explicit `enumType` on the `Column` isn't needed anymore, so I'm suggesting to omit it and just generate:
```php
#[ORM\Column]
private ?Suit $suit = null;
```
