Fix signal unregistration in grapple gun on hit (#94489)

Browse Source 
## About The Pull Request

Changes the unregistering of COMSIG_PROJECTILE_ON_HIT to
COMSIG_PROJECTILE_SELF_ON_HIT because COMSIG_PROJECTILE_ON_HIT isn't
used anywhere in grapple code but COMSIG_PROJECTILE_SELF_ON_HIT is.

See lines 70 and 71 for what I mean.

## Why It's Good For The Game

Fixes good.
