Paul Gottschling b975c0e5f5 Correct Vale lint errors in partials (#49798) 
One edge case is the `structure.architecture-h2` warning in
`docs/pages/includes/database-access/rds-proxy.mdx`. This is technically
correct, since the "How it works" section is before the "Prerequisites"
section. We can determine whether this is a bug to fix in a separate
change.
