[MIRROR] Fixes Venus Human Trap Tangle Ability (#1611)

* Fixes Venus Human Trap Tangle Ability (#82178)

## About The Pull Request

This makes the Venus Human Trap's dreaded "Tangle" ability work again!
You can also now just click on people from a range to activate it too,
instead of using the ability button.

It has been converted into a projectile attack mob ability. This
(surprisingly) didn't require any work beyond extending the ability
path. Some balloon alerts have been thrown in as well, to notify the
user when they've tried to tangle something they can't.

The max_vines var has been axed, and you can only target one user. This
is still an improvement over the current (zero) number of people you can
target with this ability. I have no idea what this var was supposed to
do because the ability has not worked since its implementation.
## Why It's Good For The Game

Closes #79848.
