[MC-275519] Programmer Art: Torches on repeaters still have unneeded bottom faces

The bug

~~MC-177452~~ was fixed for the default resource pack in 24w33a. The old repeater 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.
