Module Description: add dot to the end of the sentence

I guess given that 🐛 Using the module filter on the module list page a module can only be found by system name if the description ends with a period Needs work is fixed which I once reported as a result of this module not having a dot at the end, I guess we can now make the module consistent with everything else and add the dot ^^

Thanks for your contribution!
