fix: comment out community cheatpath in --init output (#773)

cheat --init now comments out the community cheatpath by default and
includes a git clone instruction with the resolved path. This prevents
warnings about missing directories when users save the --init output
as their config without also cloning community cheatsheets.

Closes #773
