doc: Clarify VERBOSE output for ANALYZE and VACUUM

ANALYZE VERBOSE and VACUUM VERBOSE both print per-table information
at INFO level, including the table currently being processed and
various statistics. However, the documentation described ANALYZE
VERBOSE only as displaying generic "progress messages", while VACUUM
VERBOSE used different wording about a vacuum activity report.

Reword the VERBOSE option descriptions and Outputs sections to describe
the actual output more consistently.
