Image showing grep of the nemo.desktop file showing problematic line.

Description of problem:
When installing the Nemo file manager on a Fedora system running the default GNOME desktop, there is no icon created

Version-Release number of selected component (if applicable):
Fedora 36+
nemo 5.8.3, but reproduced in previous versions



How reproducible: 
Every time Nemo is installed or updated via the Fedora updates repository.


Steps to Reproduce:
1. Install Fedora using the default GNOME desktop
2. Install Nemo file manager package from Fedora updates repository
3. Optional: Remove Nautilus file manager from locally installed packages (this makes it easier to identify)
3. Look for Files in the GNOME application "Apps" list

Actual results:
No icon is displayed called "Files" for the Nemo file manager. If Nautilus has been removed, then there are no "Files" icons shown at all.

Expected results:
As a user, I would expect a new icon to be displayed after installing a new file manager.

Either two "Files" icons will be displayed if Nautilus is installed, or an icon will be shown labeled "Files" which will launch the Nemo file manager.

Additional info:
This is caused because by default the "desktop" file (/usr/share/applications/nemo.desktop) has a line which limits which environments the icon will be displayed for. Currently, this is limited to Cinnamon and Budgie. You can comment out this line to have it display, but it must be done each time the package is updated.
