You can use a fishing rod to snatch organs during organ manipulation surgery (feat organs sanity fix) (#87774)

## About The Pull Request
This allows you to use a fishing rod during the "manipulate organs" step
of the aforementioned surgery to snatch organs from a target.

Unlike other fish sources, this one has a negative fishing difficulty of
-20, which when summed with the default minigame difficulty should still
result in a negative difficulty. In layman terms, this means the
minigame is skipped here (unless you're wearing some clunky stuff like
insulated or boxing gloves). It also has a wait time of 8 to 13 seconds
versus the more random standard 3 to 25 seconds.

A small side-effect of this is that explosions during the "manipulate
organs" step will basically disembowel you, but it kinda fits anyway.

By the by, because of this, there is a tiny chance bluespace fishing
rods can yield you random organs. Worry not, they're newly generated, so
you won't be snatching it from another player by accident (at least for
now).

## Why It's Good For The Game
It adds more possible weird and rare shenanigans involving surgery.
