[Plugin: Proper Network Activation] bump the supported version number

Hi again

Do you think you can bump the supported version number for this plugin please as it’s currently listed as supporting up to 3.2 🙂

This would also help other visitors to the plugin page to know that it’s still a good plugin

Cheers

Damien
