Documentation still mentions "Docker" as the default driver in certain places

Prerequisites

• This was not already reported in the past (duplicate check)
• It does reproduce it with code from main branch (latest unreleased version)
• I include a minimal example for reproducing the bug
• The bug is not trivial, as for those a direct pull-request is preferred
• Running pip check does not report any conflicts
• I was able to reproduce the issue on a different machine
• The issue is not specific to any driver other than 'default' one

Environment

Documentation, since change in v6

What happened

Documentation still mentions Docker as the default driver, but v6 made the "delegated" one the default, some examples include:
https://ansible.readthedocs.io/projects/molecule/getting-started/#inspecting-the-moleculeyml
https://ansible.readthedocs.io/projects/molecule/examples/#docker-with-non-privileged-user
