Added Molecule tests for atomic-red-team role.

**Added:**

- Molecule configuration - Created new `molecule` configuration files for the
  `atomic-red-team` role to support local testing and verification.
- Converge playbook - Added `converge.yml` playbook for applying the role during
  testing.
- Inventory file - Created an inventory file for Molecule testing.
- Docker platforms - Defined Docker platforms in `molecule.yml` for testing the
  role on Ubuntu, Kali, and Rocky Linux containers.
- Verify playbook - Added `verify.yml` playbook for verifying the role's
  functionality during testing.
