Desired Behavior

The delegated driver only supports a select number of Ansible connection params in the instance dict: https://github.com/ansible-community/molecule/blob/main/src/molecule/driver/delegated.py - the ansible_shell_type param is missing.

The shell type paramater is necessary in one particular use case that I can think of - testing Windows instances via SSH where ansible_shell_type: powershell must be set.

Actual Behaviour

Adding shell_type to the instance dict does not properly map into the generated molecule inventory as ansible_shell_type. This seems like an oversight - and therefore a bug.
