Poetry add help discrepancy

Issue

There is a discrepancy between the documentation when comparing poetry add --help and the webpage https://python-poetry.org/docs/cli/#add

The discrepancy is for adding a git repo using ssh:

• webpage:

  poetry add git+ssh://[email protected]/sdispater/pendulum.git
  # or alternatively:
  poetry add git+ssh://[email protected]:sdispater/pendulum.git
  

• CLI help:

   - A git SSH url (git+ssh://github.com/python-poetry/poetry.git)
  

The CLI help is missing the "git@" part.
