simple array type hint for nullable not include null

[PawelSuwinski]

Such schema:

types:
  Project:
    properties:
      shareWith:
        range: "https://schema.org/email"
        cardinality: "(0..*)"
        attributes:
           ORM\Column: { type: "simple_array" }

Will generate:

    /**
     * @var array|null
     *
     * @see _:shareWith
     */
    #[ORM\Column(type: 'simple_array', nullable: true)]
    private array $shareWith = [];

    /**
     * @return array|null
     */
    public function getShareWith(): array
    {
        return $this->shareWith;
    }
// ... adder, remover or setter

And should be

/**
     * @see _:shareWith
     */
    #[ORM\Column(type: 'simple_array', nullable: true)]
    private ?array $shareWith = [];

    public function getShareWith(): ?array
    {
        return $this->shareWith;
    }
