Pug-cli is unmaintained despite being mentioned in the readme

See the following comment on its issues:

https://github.com/pugjs/pug-cli/issues/86#issuecomment-2225076337

Getting crow-help to review @tokilabs/pug3-cli and merging their pull requests seems like a preferable alternative to just letting pug-cli waste away…

Right now people are de-facto encouraged to blindly switch to third party user's forks.
