Only pushes the latest tag for stable releases.

Previously beta releases were also pushed to latest.

This seems to do the opposite.

if echo "5.1.0" | grep -iqF beta; then                                          
  echo "stable!"                                                              
fi                                                                              

if echo "5.1.0-beta1" | grep -iqF beta; then                                    
  echo "beta!"
