* feat(tools): add seed/solution restore script * chore(curriculum): remove empty sections' markers * chore(curriculum): add seed + solution to Chinese * chore: remove old formatter * fix: update getChallenges parse translated challenges separately, without reference to the source * chore(curriculum): add dashedName to English * chore(curriculum): add dashedName to Chinese * refactor: remove unused challenge property 'name' * fix: relax dashedName requirement * fix: stray tag Remove stray `pre` tag from challenge file.

--description--
Replace the body of addChars, so that instead of adding the arguments, it returns a charRange between the first two arguments: c1 => c2 => n => charRange(c1, c2).
--hints--
See description above for instructions.
