Cleanup counter command (#1695)

- Import `Commands.literal`
- Use more readable syntax for Brigadier command
- Use `DyeColor` directly instead of toString -> fromString everywhere
  - Also updates `WoolTool` to use the new `HopperCounter` getter that supports it
- Split `resetCounter` in two, one for single and one for all

Also: HopperCounter now uses `.overworld()` and its `//OW` comments are removed
