Generator copies over whole event schema into asyncapi operations field

### I tried this:

Clone https://github.com/HansMartinJ/eventcatalog-sample-schema-generation-bug

- npm run generate

Download schema
http://localhost:3000/generated/services/service/service.yaml

### This happened:

The spec has duplicate schema definitions in channels and operations

### I expected this:

operations only has something like
```
channel:
$ref: '#/channels/target'
```

### Is there a workaround?

_No response_

### Anything else?

May prevent asyncapi visualiser from working correctly (but may also be issue with avro)
Go to http://localhost:3000/docs/services/service/1.0.0/asyncapi

Look at both operations

Only light/measuredjson has expandable schema
