Revert "Updated mappings for Forge 7.7.2.679"

This reverts commit 41163699556b5bbd111d82a153dbda2d4a11e3bf.

I didn't notice that this actually undid the correct mappings when merging this PR. This appears to use the old forge version mappings from pre-update.
Removed some crap from 77 that got brought over to 76 when when the update was cherry picked.
