Switch to https://schema.org/version/latest/schema.rdf

Schema org converted doesn't work any more,
it tries to fetch https://schema.org/docs/schema_org_rdfa.html which is not available anymore.
See https://git.drupalcode.org/project/rdfui/-/blob/8.x-1.x/src/SchemaOrgCon...

When trying to any content type, with rdfui module enabled, following exception is being thrown:

The website encountered an unexpected error.
