Add support for virtual desktops

[emarforio]

Added support for the hyprland virtual desktops plugin. I am not a Rust programmer so it it should probably only be used as a reference since I have not put much thought into this but it works. You will probably have to consider the colors for workspaces better but this works well enough for me and I will try to keep an up to date fork available if you don't want this functionality in the main project.

Closes #210

Sorry, I haven’t had time to look at this PR until now.
At the moment I don’t have a way to test the system (I don't have that hyprland plugin), but I saw that all the changes are behind a configuration flag, so nothing should break.

If it works for you, I’ll just do a quick check to make sure there are no regressions without enabling this feature, and then I think it can be merged.

I’d ask you, if you have time, to add a line in the changelog with this change, and maybe also in the site documentation.

Thanks a lot!

You no longer need to add the changelog file.

If you're able to resolve the conflict, we could proceed

Sorry for not responding earlier, life got in the way. I have merged the main branch now and moved the documentation to the website. Everything seems to work just fine still.
