Bug 511450

SUMMARY
In the flatpak integrator plugin there is a list of flatpak app ids that are mapped to the respective enum for which browser they are based on as well as their native host configuration path. 

https://invent.kde.org/plasma/plasma-browser-integration/-/blob/master/flatpak-integrator/plugin.cpp?ref_type=heads#L140  

I think we need to add [edge](https://flathub.org/en/apps/com.microsoft.Edge) and [edgedev](https://flathub.org/en/apps/com.microsoft.EdgeDev) to this for the flatpak to work. The edge flatpak is not packaged by Microsoft but it is well maintained, and Microsoft has even [recommended it's usage.](https://support.microsoft.com/en-us/topic/xbox-cloud-gaming-in-microsoft-edge-with-steam-deck-43dd011b-0ce8-4810-8302-965be6d53296) 

Is this as simple as adding an entry and specifying the correct path for the native messaging host? If so, I wouldn't mind testing it and making a pull request.

STEPS TO REPRODUCE
1. Try to use the microsoft edge flatpaks with plasma integration 

OBSERVED RESULT
Integration does not work when using edge as the flatpak

EXPECTED RESULT
Integration does work when using the edge flatpak
