feat: update checking of the package rendering vocabulary
- deprecated properties are now reported as `OPF-086`, like for other deprecated properties, instead of `RSC-017`. This means the check relies on the `Property#isDeprecated` facility, instead of custom Schematron code. - deprecated property value is checked in custom Java code the `OPFHandler30#processMeta()` method. - verify that custom properties cannot be defined using the reserved "rendition" prefix. A new feature file is added for this single test, to match the spec section ordering. Fix #1327
