cellxgene-schema must annotate schema_reference

[brianraymor]

Design

See schema_reference.

When a dataset is uploaded, CELLxGENE Discover MUST automatically add the schema_reference key and set its value to the permanent URL of this document.

schema_reference

Key	schema_reference
Annotator	CELLxGENE Discover
Value	This MUST be "https://github.com/chanzuckerberg/single-cell-curation/blob/main/schema/4.0.0/schema.md".
