DBZ-8549 Adds downstream JDBC connector deployment instructions

DBZ-8549 Adds downstream deployment instructions to the JDBC connector doc.

Tested in a local Antora build. These changes have no effect on the community version of the documentation.

This is ready for upstream review, but should not be merged yet, pending resolution of downstream build issues.

I would especially appreciate it if someone could review the CR examples. I modeled these examples after the source connector examples where I assumed that made sense, but I was unsure where to include certain entries, for example,
where do we define the topics array that lists the Kafka topics from which the connector consumes change events?

I placed this in the connector YAML examples (L753 and L994), e.g.,

spec:
  class: io.debezium.connector.jdbc.JdbcSinkConnector  // <2>
  tasksMax: 1  // <3>
  topics: // <4>
    - orders

Is that correct?

Hi @roldanbob overall this LGTM, I just left one small nit-pick.

I don't see the need to reference a "Source" in this context, as the JDBC sink connector can be used with non-database sources.

As to your question, the topics shouldn't be an array as you implemented, but AFAICT its just a connector configuration that is a comma-separated list of values in the connector configuration section, just like you would provide this as part of the JSON, as shown here.
