…e walls instead (#4136)

# About the pull request

This PR changes some of the LV624 cave walls to be jungle walls

# Explain why it's good for the game

Honestly I just think it looks pretty and mechanically nothing changes
since those jungle walls are just as unbreakable as the cave ones, I
implore reviewers to load this branch in game and check out the
difference adding just a little more tile differentiation helps the
caves visually
