dependency step installs roles to user's roles path, not in ephemeral directory

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

What happened

Hello. After update from molecule 4 to molecule 6 I mentioned that molecule now tries to install dependencies into user's roles directory, not in ephemeral directory. I tried to investigate this problem by running molecule in debug mode, and I couldn't see any debug messages in output (ANSIBLE_* and MOLECULE_* environment variables):

molecule --debug -v dependency

INFO     Using /home/user/.ansible/roles/ansible-role-dotnet-tools symlink to current repository in order to enable Ansible to find the role using its expected full name.

I think it can be related to this PR #4047

Reproducing example

No response

molecule 5.1.0 looks OK:

molecule --debug -v dependency

INFO     Using /home/user/.cache/ansible-compat/fa9621/roles/ansible-role-dotnet-tools symlink to current repository in order to enable Ansible to find the role using its expected full name.
