Port ledger: game-007 rows the piglin riding code now answers

DismountOrSkipMounting.create and isVehicleValid were mapped missing when
piglins never rode anything. Piglins now ride baby hoglins: the ride
activity mounts (piglin.rs::mount) and dismounts through
dismount_or_skip_mounting, which makes the isVehicleValid test itself, so
that row is inline.

BackUpIfTooClose.create cited the goal struct where map-check wants a fn;
it now cites too_close, the fn that holds the create(5, 0.75) check.

The other missing rows in the file (SteppedInterpolationTracker.addStep,
updateTracking, getPositionPath, AttributeMap.assignAllValues,
assignBaseValues, assignPermanentModifiers, AnimalPanic.lookForWater) were
checked again and are still absent, so they are left as they are.
