Update 'Using Proxies' documentation

[KhalfaniW]

https://github.com/OokTech/TW5-Bob/blob/master/Documentation/Using%20Proxies.tid

The documentation shows an example of caddy server config.
The example does not forward websockets.

phone.local:8080 {
  tls /data/data/com.termux/files/home/etc/phone.crt /data/data/com.termux/files/home/etc/phone.key
    proxy /wiki 127.0.0.1:8090 {
    without /wiki
  }
}

Here is my caddy server config that forwards websockets and doesn't have tls.

example.com:8081 {
    tls off
    proxy /wiki example.com:8080 {
    websocket 
    without /wiki
    }
