Remove collision on minehole's ladder

[Matheusmk]

The minehole's ladder collision serves no purpose other than to get in our way. It doesn't balance anything gameplay-wise, it's there only to get you or some other structures stuck. My suggestion is to remove the collision (just like legacy if im not mistaken), and if someone has any reason why it should stay I would very much like to discuss about it.

Ladder only exists to be frustrating, which is great when eventually you're expected to go up/down 9 of em with a cart
