Bioschemas dump uses undefined `schema` prefix

[AlasdairGray]

The data dump includes multiple instances where the prefix schema is used instead of sc. These result in the corresponding data being generated with the incorrect IRI for two types.

• schema:Organization
• schema:Person

Looks like it's been solved (biotools dump here), no occurrence of schema:prefix
