Docker driver with new molecule version {'driver': [{'name': ['unallowed value docker']}]}

[MosheBlumbergX]

Describe the issue

When installing molecule docker, with molecule version > 3.1.0 the following error takes place when trying to run a playbook test:

{'driver': [{'name': ['unallowed value docker']}]}

pip install molecule docker

To Reproduce

Install molecule version > 3.1.0

pip install molecule docker
$ molecule converge -s plaintext-basic-rhel
..
..

CRITICAL Failed to pre-validate.

{'driver': [{'name': ['unallowed value docker']}]}

This is due to:
ansible/molecule#2811
ansible/molecule#2891

To resolve:

pip3 install molecule-docker

Molecule seems to be changing all the time, in the official docs: https://molecule.readthedocs.io/en/latest/installation.html#install

it says to go with

python3 -m pip install --user "molecule[docker]"
