Ansible Lightspeed view should be more informative when it's not enabled

[TamiTakamiya]

Problem

This is the continuation of #1442, which reported a bug that Ansible Lightspeed view on the sidebar displayed "undefined". #1442 also suggested:

Maybe a suggestion to enable Ansible Lightspeed in Settings.
That part was not included in previous releases and is condered as an enhancement. So it was separed from #1442.

Solution

1. Update the message shown in Ansible Lightspeed view on the sidebar when Lightspeed is not enabled in Settings
2. Implement the logic to change the message when user updates the Lightspeed settings as difference messages need to be shown depending on settings.

Alternatives

N/A

Additional context

Similar logic may be implemented for the Ansible Lightspeed Feedback view as well.
