burp.cfg client for burp-ui example is wrong in ssl_cert_ca

Hello Ziirish,

I have noticed that this example is creating problems with burp certificates: https://burp-ui.readthedocs.io/en/stable/step-by-step.html#burp2-server

Lines:

    # SSL certificate authority - same file on both server and client
    ssl_cert_ca = /etc/burp/ssl_cert_ca.pem

ssl_cert_ca must be different for client and server, at least in the next link and in my tests if they are same it breaks burp-ca.

Check this message:

Kind regards, Pablo.
