Fix invalid anyOf usage in schema generation

The schema currently defines anyOf as an object instead of an array, which is invalid. Spectral linting (docker run --rm -it -v $(pwd):/tmp stoplight/spectral:6 lint /tmp/openapi.yaml) reports:

"anyOf property must be array."

This PR wraps $schemas with array_values, ensuring anyOf receives an array. The same approach is already used in other parts of the code.

Oh wow thanks for the fix! Could provie your Resource that leads to that? I'd like to add this to our test to ensure no regression (I can handle this).

@soyuka I got this error on this rather exhaustive field :

/**
* @var array<array-key, string|numeric|bool|string[]|null>
*/
#[Groups(groups: ['item:user:read', 'item:user:write'])]
#[ORM\Column(type: 'jsonb')]
private array $preferences = [];
