[DOC] Add `/ws` for nginx websocket configuration

### What is this PR for?
It's a bit misleading that both regular webserver location and websocket location use the exact same address. It's better to specify that websocket requests should be proxy-passed to  `/ws` subdirectory.

### What type of PR is it?
Documentation

### Questions:
* Does the licenses files need update? no
* Is there breaking changes for older versions? no
* Does this needs documentation? no

 Another option is to have an authentication server that can verify user credentials in an LDAP server.
 If an incoming request to the Zeppelin server does not have a cookie with user information encrypted with the authentication server public key, the user
 is redirected to the authentication server. Once the user is verified, the authentication server redirects the browser to a specific URL in the Zeppelin server which sets the authentication cookie in the browser.
-The end result is that all requests to the Zeppelin web server have the authentication cookie which contains user and groups information.
