fix(deps): correct apple-privacy-manifests plugin id in the catalog

The catalog declared org.jetbrains.kotlin.plugin.apple-privacy-manifests,
which does not exist — the real id is
org.jetbrains.kotlin.apple-privacy-manifests (no '.plugin'; Portal
serves its marker, the typo'd id 404s). Nothing applies the alias yet
(parked for App Store ITMS-91053 compliance), so the build never
noticed; the only symptom was Renovate's 'Package lookup failures'
warning on the Dependency Dashboard, which silently left the entry
un-renovated.
