Programmer Art: Torches on comparators still have unneeded bottom faces

Relates to: MC-275515 MC-275520

The bug

MC-177453 was fixed for the default resource pack in 24w33a. The old comparator models were moved to the Programmer Art resource pack, however, and this existing issue was not fixed for them.

How to fix

A resource pack is attached to this ticket that fixes this issue entirely. Mojang have my full permission (and encouragement) to use these resources or their derivatives to fix this issue.
