Come out of maintenance mode before doing translations during a deploy

Hmmm this is not possible because the locale part happens before config import... from the docs

  /**
   * Ensures that translations are updated as part of a drush:deploy command.
   *
   * Translations are imported prior to configuration to ensure that the
   * configuration is the final say as it is very confusing when configuration
   * changes after running an import.
   *
   * @hook post-command updatedb
   */
  public function postUpdateDbHook(int $result): void {

And I think we need to be in maintenance mode during config import.... therefore closing this as won't fix. I think the real fix is to make the locale code much faster...
