Add aoe tag to freezing pulse

Cause this skill sucks at selfcasting, i don't understand why additional proj making this skill overlapping instead of proper spreading. Also, pinpoint support sucks with intensity loosing mechanic for mapping. Hire at testing dudes, who actually play poe on 97-100 char skill leveI, it's 0 effort how you are testing in devkit with your slow playstyle on white maps. It would be good, if this skill was reworked at all, it's cleave but for int chars
