tooltips: simplify coin tooltips (Numismatics already shows value), include sprocket, 0.22.3 -> 0.22.4

Three corrections per user feedback:
1. Drop the conversion-crib lines -- Numismatics' built-in tooltip
   already shows 'Value: N spurs' so our added lines were duplicate.
2. Include sprocket (numismatics:sprocket) -- the 6th denomination
   I missed when first writing the script. Full set: spur, bevel,
   sprocket, cog, crown, sun.
3. Keep only the actually-useful hint: 'Right-click a Bank Teller
   block to convert denominations' -- the one piece of info that
   isn't on the mod's own tooltip.

Decision punted (deliberately): no 8-spurs-shapeless-to-1-bevel
crafting recipes. The Bank Teller is the spawn-economy anchor;
crafting recipes would let players bypass the bank entirely. Players
who want local conversion can place their own Teller -- which is the
intended Numismatics design.
