Using env in a molecule.yml isn't processed as it's marked as an array

Issue Type

Using env in a molecule.yml isn't processed as it's marked as an array. Adding a - to the list doesn't solve it either.

Molecule and Ansible details

  python version = 3.8.10 (default, Jun 22 2022, 20:18:18) [GCC 9.4.0]
  jinja version = 3.1.2
  libyaml = True
molecule 4.0.2 using python 3.8 
    ansible:2.13.5
    delegated:4.0.2 from molecule
    docker:2.1.0 from molecule_docker requiring collections: community.docker>=3.0.2 ansible.posix>=1.4.0

Molecule installation method (one of):

• pip3 using a cloudinit config

Ansible installation method (one of):

• pip using a cloudinit config

Detail any linters or test runners used:

Desired Behavior

Before the latest patch, the molecule container was created fine and ansible ran fine on the created container.

Actual Behaviour

We are using an openldap container (docker.io/osixia/openldap:1.4.0) which requires several environment inputs:

env:
  LDAP_ORGANISATION: "blabla"
  LDAP_DOMAIN: "bla.local"
  LDAP_ADMIN_PASSWORD: "reallygoodpassword"
  LDAP_READONLY_USER: "true"
  LDAP_READONLY_USER_USERNAME: "bla_user"
  LDAP_READONLY_USER_PASSWORD: "reallygoodpassword"

When the run starts we see an error that this list isn't an array.

CRITICAL Failed to validate /default/molecule.yml

["{'LDAP_ORGANISATION': 'blabla', 'LDAP_DOMAIN': 'bla.local', 'LDAP_ADMIN_PASSWORD': 'reallygoodpassword', 'LDAP_READONLY_USER': 'true', 'LDAP_READONLY_USER_USERNAME': 'bla_user', 'LDAP_READONLY_USER_PASSWORD': 'reallygoodpassword'} is not of type 'array'"]

So we added a "-" in front:

env:
  - LDAP_ORGANISATION: "blabla"
  - LDAP_DOMAIN: "bla.local"
  - LDAP_ADMIN_PASSWORD: "reallygoodpassword"
  - LDAP_READONLY_USER: "true"
  - LDAP_READONLY_USER_USERNAME: "bla_user"
  - LDAP_READONLY_USER_PASSWORD: "reallygoodpassword"

The molecule run starts, however the container creation now fails with the error:

argument 'env' is of type <class 'list'> and we were unable to convert to dict: <class 'list'> cannot be converted to a dict

We also tried to put the env vars into a separate env.yml file, but this didn't work either.
