doc: Make UPDATE FROM examples consistent

The original first half of the example used an employees table and an
accounts.sales_person foreign key column, while the second half (added
in commit 8f889b1083f) used a salesmen table and accounts.sales_id
for the foreign key.  This makes everything use the original names.
