Radio controls guidebook entry (#13990)

* Added radio guidebook entry with channel designators

* Radio guidebook update

* Update Resources/Server Info/Guidebook/Controls/Radio.xml

Oh yeah, I definitely can see where a change to the radio_channels.yml would cause a desync here. I will need to look into how to link the xml to Resources\Prototypes\radio_channels.yml
