Fix jsonschema (#805)

Using `#[serde(rename="camelCase")] on an enum renames the enum tag, not
the enum fields.
For that, we have `rename_all_fields`.

Turns out, that is not supported by schemars 0.8, which is the version
used by ndc models.

So, this PR users `#[serde(rename)]` on the individual fields.
