Subject: [PATCH v1] doc: Fix memory context level in
 pg_log_backend_memory_contexts() example.

Commit d9e03864b6b changed the memory context level numbers shown by
pg_log_backend_memory_contexts() to be 1-based. However, the example in
the documentation was not updated and still used 0-based numbering.

This commit updates the example to match the current 1-based output.
