[Q] Websockets protocol: inconsistency between the doc and the code

[SP-937-215]

Hello,

There is an inconsistency between the code and the doc regarding the websocket protocol.

In the documentation here it is the secured protocol with "wss" while in the docker-compose file row 89 it is the unsecured version : "ws".

It is very minor but can be misleading for someone unable to understand what it means in terms of setup.
