Add diagram of an Ethernet cable and port to net-wired-connect.page
On https://gitlab.gnome.org/GNOME/gnome-user-docs/-/blob/master/gnome-help/C/net-wired-connect.page, it would be helpful if there was a diagram of an Ethernet cable and port, as new computer users may not be familiar with them (or how to distinguish an Ethernet cable from a HDMI cable). It would be useful to indicate where users might find the Ethernet port on common desktop/laptop layouts (i.e. it’s often on the side of a laptop, and near the top of the back of a desktop).
This is based on feedback from Endless OS users.
