SchemaViewer cannot view external json schema

### I tried this:

clone https://github.com/HansMartinJ/eventcatalog-sample-schema-generation-bug
verify that asyncapi-files/service.yaml has correct format and refs external json schema

`npm run generate`

go to http://localhost:3000/docs/events/lightmeasuredmessagejson/1.0.0

### This happened:

Shows no schema defined

### I expected this:

Schema rendered

### Is there a workaround?

The generated schema in events/lightMeasuredJson wraps original schema in "schema" field, remove this (and schemaFormat). Then it works

### Anything else?

Avro is also wrapped in schema field. But component manages to render it.

Config:
asyncAPI: {
renderParsedSchemas: false // default is true
},
saveParsedSpecFile: true,
parseSchemas: false,
