new voicelines for Wattson's ultimate

this is something small but i feel can make a good quality of life improvement for callouts and pings.

basically i wanted to suggest adding ping voicelines for Wattson's ultimate similar to how they have some for Revenant's totem (being able to call out enemy pylons, warning that a friendly pylon has been destroyed or where the friendly pylon is) this can also be taken a bit further by having quips for when enemy bombardments are coming in to have the legends say something like "Airstike! Get to the pylon!" or "grenades! stay near the Pylon!" and yeah that last suggestion can just be for wattson but it would be pretty cool  to have it for other legends in my opinion.
