Export content test examples as JSON #1772
Description
We have a nice library of examples of Zulip message content in our tests, on the ContentExample and KatexExample classes in test/model/content_test.dart and test/model/katex_test.dart .
It'd be nice to export that test data in a JSON format. This would be useful for re-using the same test data in other Zulip codebases.
To do this, we can use package:json_annotation and package:json_serializable on the ContentNode subclasses, the same way we do for the JSON in the Zulip API.
