Not possible to add message examples when references are used

[grahambull-newday]

Describe the bug

It's not possible to add message examples when references are used. I'm pretty sure the JSON below meets the AsyncAPI specs.

How to Reproduce

Here's a complete example that, when pasted into the studio, gives 4 errors (NOT SUPPORTED: keyword "id", use "$id" for schema ID) and some warnings (ignore these).
The output is from asyncapi/saunter, integrated into a C# web app, but with names changed. The only real change is the additional of the examples block in the message. I'm pretty sure it's all valid, according to the spec. Saunter outputs the references used in the message's definition.
