Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

1 - Create a project with some routes using go_router.
2 - Add the logging package.
3 - Call this code to output all logs:

void setupLogging() {
  Logger.root.onRecord.listen((record) {
    final String message;
    final messageHeader = '${record.level.name}: ${record.time}: ${record.message}';
    if (record.level < Level.SEVERE) {
      message = messageHeader;
    } else {
      message = '$messageHeader : ${record.error} : ${record.stackTrace}';
    }

    if (kDebugMode) {
      print(message);
    }
  });
}

4 - You will see GoRouter prints all the known routes when the app starts up.

This is happening because RouteConfiguration calls log.info(debugKnownRoutes()) on it's constructor

Expected results

No logs should be created if debugLogDiagnostics is false. This excessive logs will add irrelevant information to monitoring tools.

Actual results

Logs are being printed when debugLogDiagnostics is false.
