fix(db-postgres): nested arrays with localized items and versions

[r1tsuu]

Port of #8331 to 2.0

Previosuly, trying to append a new item to an array that contains another array with localized items and enabled versions led to a unique _locale and _parent_id error

{
  name: 'nestedArrayLocalized',
  type: 'array',
  fields: [
    {
      type: 'array',
      name: 'array',
      fields: [
        {
          name: 'text',
          type: 'text',
          localized: true,
        },
      ],
    },
  ],
}
