fix: change the prefix for https://schema.org/ back to schema` (#2312)

aucampia · web-flow · commit 3faa01bf1691 · 2023-03-25T18:46:05.000+01:00
The default prefix for `https://schema.org/` registered with `rdflib.namespace.NamespaceManager` was inadvertently changed to `sdo` in 6.2.0, this however constitutes a breaking change, as code that was using the `schema` prefix would no longer have the same behaviour. This change changes the prefix back to `schema`.
