### Which parts of the documentation do you think need improvement?

_No response_

### Affects Version(s)

master

### Improving the documentation

the example of ranger-spark-audit.xml in document:
https://kyuubi.readthedocs.io/en/latest/security/authorization/spark/install.html#ranger-spark-audit-xml

as ranger document says : [Audit to DB will not be available from 0.6 version](https://cwiki.apache.org/confluence/display/RANGER/Audit+to+DataBase).
so config property about xasecure.audit.destination.db* maybe could remove from kyuubi's document

### Anything else

_No response_

### Are you willing to submit PR?

- [ ] Yes. I can submit a PR independently to improve.
- [ ] Yes. I would be willing to submit a PR with guidance from the Kyuubi community to improve.
- [ ] No. I cannot submit a PR at this time.

Open the linked Spark authorization installation page and locate the ranger-spark-audit.xml example. Compare its xasecure.audit.destination.db* settings with the linked Ranger audit documentation, then update the example if those settings are obsolete. Done means the Kyuubi documentation no longer advertises unavailable database-audit configuration.
