[Suggestion] Add language to Winston pixel spray about Hammond mines

[trixter13]

After struggling for a few days to get Winston's pixel spray, I accidentally got it while shooting Hammond's ult mines. These apparently count for the achievement and are a much easier way than hoping that the enemy picks a Sym or Torb. It isn't obvious, at least to me, as mines are more of a weapon than a trap or turret that can collectively trap someone but not individually.

I think it would be helpful to add language to the spray's description that included the mines so that it is more clear. The current description is straight off of the wiki but it is still not very clear. Something like, "Destroy 10 turrets, traps, or mines using Winston's Tesla Cannon without dying in quick or competitive play." would be more clear.

I'm not sure if Junk's concussion mines count towards the achievement but if they do, this description would be even more helpful.
