fix!: plugin-search with localization enabled (#8938)

The search plugin was incorrectly retrieving all locales, when it should
just be retrieving the locale of the parent document that was actively
being updated.

## BREAKING CHANGES:

If you have a localized Payload config, and you are using the `plugin-search`, we will now automatically localize the `title` field that is injected by the search plugin and this may lead to data loss. To opt out of this new behavior, you can pass `localize: false` to the plugin options.

 The `collections` property is an array of collection slugs to enable syncing to search. Enabled collections receive a `beforeChange` and `afterDelete` hook that creates, updates, and deletes its respective search record as it changes over time.
 
+### `localize`
+
+By default, the search plugin will add `localization: true` to the `title` field of the newly added `search` collection if you have localization enabled. If you would like to disable this behavior, you can set this to `false`.
+
 #### `defaultPriorities`
 
 This plugin automatically adds a `priority` field to the `search` collection that can be used as the `?sort=` parameter in your queries. For example, you may want to list blog posts before pages. Or you may want one specific post to always take appear first.
