### Summary

```(venv) ➜  ansible-navigator git:(main) ansible-galaxy collection install cisco.ios -p ./collections
Starting galaxy collection install process
[WARNING]: The specified collections path '/Users/bthornto/github/ansible-navigator/collections' is not part of the configured Ansible collections paths '/Users/bthornto/.ansible/collections:/usr/share/ansible/collections'. The installed collection won't be
picked up in an Ansible run.
```
It will be picked up in an Ansible run, in fact playbook adjacent collections are fully Supported.

Can `, unless within a playbook adjacent collections directory` be added to the message?
