Bug#987119: godot3: Name of .desktop file causes odd behavior in some DEs

[egg]

Package: godot3
Version: 3.2.3-stable-1+b1
Severity: minor
X-Debbugs-Cc: xerographic.paper at protonmail.com

Some desktop environments, such as KDE Plasma and Cinnamon, have icon-based
taskbars which group windows into a single icon.

Usually, when a pinned application is opened from this kind of taskbar, the
function of the icon switches from opening the application to maximizing
/minimizing/switching through running instances of the application. This 
happens in such a way that instances of the application are grouped 
together in a single icon.

It is somewhat difficult to explain, but in any case, godot3 does not seem
to behave as expected with these taskbars. Instead, once a project is opened
in godot3, the icon in the taskbar appears to duplicate, such that the running
instance of godot3 shows up separately from the pinned icon.

It seems that the fix is to change the name of the .desktop file from
"godot3.desktop" to just "godot.desktop"
