schema version

[TorecLuik]

In the example, schema-version only says a version number.

But I have to identify that this descriptor.json is in fact a "biomero-schema" in my reader.

So, like the older "cytomine-0.1", it should describe not just the version but also the name of the schema.

E.g. "biomero-0.1".

Besides, that schema version should somehow be related to this pydantic implementation right? It should be hardcoded somehow based on the github release or whatever?

Or some other URL field that indicates what schema is being used by this implementation
