ISSUE-10421: [Doc] Contribute the Presto (Trino) connector to the Trino project

[sijie]

Original Issue: apache#10421

---

Background: below are some of the discussions from the Pulsar Mailing List.

We have talked to the Trino community about contributing the Presto/Trino
connector to the Trino project. The Trino community is happy to accept the
connector. So we will stop the work of moving the presto connector out of
the main repo for PIP-62. Instead, we will focus on contributing the presto
connector to the Trino project. After that is done, we will remove the
presto connector from the master.

We will try to make it before the 2.8.0 release. If we can't make it, we
will still release the presto connector for 2.8.0 and remove it once it
lands in upstream Trino.

Marvin is doing the heavy-lifting work on contributing the connector. He
might need your help on the documentation part.
