[TomasVotruba]

• Ref Fix doctrine join table annotation to attribute rector #2740
• Closes Doctrine Annotation to Attributes - InverseJoinColumn is converted to JoinColumn rector#7346
• Ref Attempt to fix incorrect doctrine table attribute values on php 8.1 #2699
• Ref Annotation to attributes rector isn't complete rector-doctrine#116
• Ref Incorrect behavior of AnnotationToAttributeRector PHP 8.1 rector#7163

It was a naughty case, so it took the all-day effort to rewrite this rule from scratch 😪

It was lot of work, but now it is finally possible to deal with unwrapping of Doctine annotation to attributes 🥳 👍

Before

    /**
     * @ORM\JoinTable(name="join_table_name",
     *     joinColumns={
     *          @ORM\JoinColumn(name="target_id"),
     *     },
     *     inverseJoinColumns={
     *          @ORM\JoinColumn(name="another_id")
     *     }
     * )
     */
   private $collection;

↓

After

    #[ORM\JoinTable(name: 'join_table_name')]
    #[ORM\JoinColumn(name: 'target_id')]
    #[ORM\InverseJoinColumn(name: 'another_id')]
    private $collection;

Let's merge this first to update the Doctrine package 🙂
