Subject: [PATCH] youtube channel urls can also be @channelname

an example this https://www.youtube.com/channel/UCKjaXKTMQMgpyac7WsnNrKw and https://www.youtube.com/@alangomezok are the same, it also crashed because it didn't match, the old url template, but it looks like that is already fixed

hope this helps, my first proposed change :)
