Describe the bug you're encountering

This is a follow-up to PR #6236. The syntax highlighting feature added in that PR does not apply to object parameters in OAS3 definitions.

To reproduce...

1. Create a gist containing the definition above and load it into https://petstore.swagger.io.
2. Expand the operation and see how the params parameter is displayed.

Expected behavior

Code examples in parameters should use the same syntax highlighting as request/response bodies.
