suggest xdg-utils to install *.desktop

[Rudxain]

This seems more cross-platform, despite depending on a package that isn't coreutils.

Note

It seems --size can't be omitted

On my GNOME install, xdg-desktop-icon install seems to simply cp the shortcut to ~/Desktop instead of ~/.local/share/applications.

I'll revert that cmd only, as xdg-icon-resource install seems to work as intended

I think this is a bit confusing as is. There are three lines in one code block with no commentary about whether all three are needed or not. Simply commenting one line doesn't communicate that it is an option or why you would use that option. I had to expand the review discussions in this PR to understand what was going on.

Can we summarize the comments in this PR in the document itself?

What about something along the lines of this? :

Use the xdg-* alternative if cp doesn't work for your system.

I have looked at this thread and can't find an explanation of why cp would not work on anyone's system? I think using xdg-utils is a fantastic idea, how about having first the xdg-utils option, and then in a comment the cp option? If some systems have some quirks with xdg-utils then people can use the cp option. Like the following, but for everything:

xdg-icon-resource install --novendor --size 256 contrib/helix.png # cp contrib/helix.png -- "$HOME/.icons" # or "$HOME/.local/share/icons"

On Debian 12 the following are all installed by default, how about Ubuntu?

$ xdg- (press tab for completion)
xdg-dbus-proxy            xdg-desktop-menu          xdg-icon-resource         xdg-open                  xdg-settings              xdg-user-dirs-gtk-update  
xdg-desktop-icon          xdg-email                 xdg-mime                  xdg-screensaver           xdg-user-dir              xdg-user-dirs-update

why cp would not work

The problem isn't that cp itself won't be available or might fail, the actual problem is that the hard-coded destination path may not be "especial", so using xdg guarantees the copy will have the desired effect (rather than being no-op)

BTW, could I (please) amend the last commit? I want to use my GH email rather than the placeholder, but that requires a force-push
