Fix warning message to show precise jump back in time duration

[AddisonFarley]

🦟 Bug fix

Fixes #2407 (Incorrect warning msg when sim jumps back in time)

Summary

Refactor the following warning message code:

if (_info.dt < std::chrono::steady_clock::duration::zero())
  {
    gzwarn << "Detected jump back in time ["
        << std::chrono::duration_cast<std::chrono::seconds>(_info.dt).count()
        << "s]. System may not work properly." << std::endl;
  }

to:

if (_info.dt < std::chrono::steady_clock::duration::zero())
{
  gzwarn << "Detected jump back in time ["
         << std::chrono::duration<double>(_info.dt).count()
         << "s]. System may not work properly." << std::endl;
}
