Instructions for installing molecule in book missing the docker plugin installation

I saw you fixed the molecule README. I saw you fixed the CI job. I even see the automated CI job recipe later in the book installing it.

But I still see in the latest edition that the initial instructions for installing molecule is missing the plugin. You have:

Molecule is easy to install:

bash复制

pip3 install molecule

You proceed to create the molecule.yml file with the docker driver and call molecule test. In between, there are no steps to install the molecule-plugins[docker] package.

Got me puzzled for the weird message that molecule gives when it is not installed.
