@Kyuyrii your changes as is are here.

This works successfully in my testing. However, when links from an existing install exist it will still leave stale links in the applications directories (the cp fails since the files refer to same thing).

I can iterate on this further to fix that issue if you'd like, if not, update your original PR and I can pull in any changes into this one when ready.

I made a modification to remove the links from the Applications and Icons folder before copying the files into it.

I made other modifications to remove parts that are no longer necessary:

@Kyuyrii I can't request you to review for some reason, so just leave a comment or reaction with your approval.

I think we should keep what you removed in f5c5ed5 for now.

There's no point in keeping them because the code won't be able to differentiate between .desktop files generated by the Snap version and the deb version.

And there's no need to change the command for the Snap version of Steam to be opened by these .desktop files, since when the deb version isn't installed, the Snap version is opened with the steam command.

Yeah I'd like to keep it if possible, but I don't see a good way for it to work with this linking method. Maybe something to revisit in the future, but we don't need to do it for this PR.
