[Task] Support link to FAQ from Dubbo logger

Related issue #10154

Status: to be planned

Background: The Logger abstraction layer that Dubbo relies on provides log output capability, but most of the exception logs do not have troubleshooting instructions, so users cannot handle the exception after seeing the exception.

Solution: By improving the FAQ and other documents in the official documents, when the Dubbo log framework outputs abnormality, it will also output the corresponding official website description link, so as to guide users to conduct independent investigation.

The issue identifies Dubbo's Logger abstraction and official FAQ documentation as the entry points, but names no files or tests. First trace how exception logs are emitted and map them to the relevant FAQ pages. Done means abnormal logs include corresponding official links and the FAQ guidance is available; confirm which exceptions and link format are in scope.
