remove alias ladder_piercing (3878) -> frenum_ladder (3530)

Reason: I can't understand how this got through: topic #31560
guiche_ladder is also a ladder piercing.
post #3142623
And scrotum ladders are a thing too, even though we don't have this tag on e621 yet.
post #2488510
There are sheath piercings, that look like a ladder
And I'd also consider multiple industrial_piercings, on the ear, a ladder piercing.
post #2798967

these implications should be added afterwards:
imply frenum_ladder -> ladder_piercing
imply gauche_ladder -> ladder_piercing

And maybe:
imply scrotum_ladder -> ladder_piercing
imply sheath_ladder -> ladder_piercing

This makes sense, I thought I already saw a request to unalias this before but I can't find it now..
