docs/quickstart.md: some instructions not clear.

[ghsnd]

At Publishing your first LDES:

• Step 3: there is no link to the Apache NiFi configuration file.
• Step 4: the instruction 'Kafka topic' is a bit unclear... should we start a Kafka Topic?

In addition to the above,

• one may want to inform readers upfront that they need to run the code in UX. Otherwise, they may fail on the LDES Client docker container.
• When accessing GraphDB via https://localhost:7200/ with FireFox, an error was raised complaining

  
  Secure Connection Failed

An error occurred during a connection to localhost:7200. SSL received a record that exceeded the maximum permissible length.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG

have to use http://localhost:7200/

We have revised the second quick start example to make it clearer for the reader. In the updated version, we have changed the title into the section titled "Starting from a published LDES" to reflect the fact that the LDES is already published in example 2, which was not clear before.

Thank you for the feedback! We have changed this in the tech docs.
