Editor: Include user's name in the wp_refresh_post_lock() response.

This ensures that the post lock data returned by the Heartbeat API is consistent.

Previously, `wp_check_locked_posts()` was updated to return the name of the user currently editing the post, but the `wp_refresh_post_lock()` response did not get a similar change.

Follow-up to [53070].
