[Bug]: Setting property not nullable results in a nullable property

Description

When setting a #[Property] changing the type of the property, nullable is ignored and the result json makes the property nullable:

This is my code:

class UserStyleDto extends AbstractDto
{
    private StyleDto $style;
    #[Property(ref: new Model(type: CodeCaptionDto::class), nullable: false)]
    private StyleLevelEnum $level;

    public function __construct(UserStyle $userStyle)
    {
        $this->style = new StyleDto($userStyle->getStyle());
        $this->level = $userStyle->getLevel();
    }

    public function getStyle(): StyleDto
    {
        return $this->style;
    }

    public function getLevel(): StyleLevelEnum
    {
        return $this->level;
    }
}

To make $level not nullable, I have to add #[Assert\NotNull].

If I don't use the #[Property] then the $level is not nullabel correctly.

I have a Normalizer that normalizes the StyleLevelEnum to a CodeCaptionDto.
