Note wayland incompatibility for resolution detection

[o0nd7ots]

Description

I was running into trouble because Neofetch showed 16:9 resolution while I was working on another one. I have found the #2371 issue and there someone wrote that Neofetch does not support connecting to Wayland display server. I think that it should be noted somewhere within the readme file.
