fix(lint): state the react-prop-deprecated warning's reason in words, not a tracker number

The react-prop-deprecated finding message ended by citing a tracker number
that no longer resolves. It now says what that decision was: the react tier
converges on the metadata-tier vocabulary, so the deprecated spelling keeps
working through the deprecation window and is removed after it. The tag, prop
and replacedBy interpolations are unchanged, as are the rule id, severity and
hint.

The sibling-package prose-id baseline shrinks by exactly that one pinned site,
regenerated with the gate's own --census-ledger.

+The `react-prop-deprecated` warning states its reason in words instead of citing a tracker number
+
+The finding `validateReactPageProps` reports for a react-page prop written in a
+deprecated react-tier spelling used to end by pointing the author at an issue
+number that no longer resolves. It now says what that decision was, in the
+sentence being read: the react tier converges on the metadata-tier vocabulary,
+so the deprecated spelling keeps working through the deprecation window and is
+removed after it. The block tag, the prop and the canonical metadata-tier
+spelling it names are unchanged, and so are the rule id, the `warning`
+severity, the hint and every other finding.
