/**
 * Overrides the default REST controller for autosaves to fix real-time
 * collaboration on draft posts.
 *
 * When RTC is enabled, regular draft autosaves are stored as revisions instead
 * of updating the parent post based on its lock and author. Auto-drafts are
 * still promoted to drafts.
 *
 * Only overrides when RTC is enabled and autosave_rest_controller_class is not
 * explicitly set, i.e. when WP_REST_Autosaves_Controller would be used by
 * default. Post types with their own specialized autosave controller (e.g.
 * templates) are left alone.
 *
 * @param array $args Array of arguments for registering a post type.
 * @return array Modified array of arguments.
