create_virtualenvs: true not working

[lmmentel]

I tried to set the create_virtualenvs: true with

        uses: dschep/install-poetry-action@v1.3
        with:
          create_virtualenvs: true

on ubuntulatest but got

Unexpected input(s) 'create_virtualenvs', valid inputs are ['version', 'preview']

Probably related to #9
