In the VisualScripting Preference window, we've hardcoded some assemblies that can be relevant for the users to use. Some assemblies come from packages (i.e Cinemachine). Even if the assemblies are not installed they still appear in the list. A side effect of this is that as they not installed, we can't know if they have a dependency on an Editor assembly so we can't display the warning icon next to them.

{*}STR{*}:
* Create a new project
* Make sure Cinemachine is not in the manifest nor installed locally.
* Open the project
* Open the Visual Scripting Preferences windows

*Actual Behaviour*

In the assemblies list Cinemachine is displayed.

*Expected Result*

Cinemachine is not listed.

*More to test:*
* Once the problem is fixed and Cinemachine is not in the list anymore
* Open the Package Manager
* Install cinemachine
* Open Visual Scripting Preference window
* Cinemachine should now be in the list. No need to manually add it as it is in the list by default.
