fix: Element inspector AI reference now works in Cursor (#1809)

#1732 used to only work in VSCode. This PR makes it work in Cursor. 

Support for other editors will be introduced in a separate PR, as right
now, this feature cannot even be enabled on editors other than VSCode or
Cursor due to how feature permissions & licensing are implemented.

### How Has This Been Tested:

### How Has This Change Been Documented:

TBD: Will see if docs need updating
