Render examples when hyperschema link description is empty

The truthy guard on `hyperschemaLink.description` skipped
`buildLinkDescription` entirely, so links with no prose but with
appended (non-inline) examples — e.g. `plugins.create` — rendered
nothing. `buildLinkDescription` already handles empty descriptions, so
call it unconditionally.
