updating docker container default paths for logs,report,data

Issue #1494

I didn't edit the part regarding cert.key

or for secured connections (TLS/SSL), please ensure your configuration file
contains the following lines:

    ssl-cert /srv/data/domain.crt
    ssl-key /srv/data/domain.key
    ws-url wss://example.com:8080

I'm not sure about those paths.

This part of the readme used to instruct to run the docker container without specifying any command. For me, this is no longer working, I have to specify a command.

So this part is now a bit redondant with the below part talking about command that can be passed to customize behavior.

Merged. Thank you for submitting this PR!
