doc: Update pg_upgrade documentation to match recent description changes.

Browse Source 
Commit 792353f7d5 updated the pg_dump and pg_dumpall documentation to
clarify which statistics are not included in their output. The pg_upgrade
documentation contained a nearly identical description, but it was not updated
at the same time.

This commit updates the pg_upgrade documentation to match those changes.

Backpatch to v18, where commit 792353f7d5 was backpatched to.
