fix(db-postgres): localized items in arrays with versions (#8334)

Port of https://github.com/payloadcms/payload/pull/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
```ts
{
  name: 'nestedArrayLocalized',
  type: 'array',
  fields: [
    {
      type: 'array',
      name: 'array',
      fields: [
        {
          name: 'text',
          type: 'text',
          localized: true,
        },
      ],
    },
  ],
}
```
