feat: Enable bridge websockets by default for new installs (#7781)

* feat: Drops multiplexing support by default.

* fix: Fix purge of jitsi-meet-prosody.

Clean the accounts when there is a - in the domain name.
Removes the certificate so reinstall will not cause problems.

* feat: Enables bridge websockets by default.

* fix: External-ip conflicts with denied-peer-ip.

In cases where the bridge and coturn are on the same machine and the local address is any of the networks from denied-peer-ip, coturn is not using its public address to probe it and communication fails as the other address is deneid.

* squash: Fix a comment.

config.js

     // 'datachannel'), undefined (treat it as 'datachannel') and false (don't
     // open any channel).
     // openBridgeChannel: true,
+    openBridgeChannel: 'websocket',
 
 
     // UI
