Add source reference on Envelope.parameterType

[jkronegg]

🤔 What's the problem you're trying to solve?

When implementing a plugin, I can determine the source reference of a Step Definition (using handler on Envelope.stepDefinition), but I cannot determine the source reference for a ParameterType.

The cause is CachingGlue.emitParameterTypeDefined which creates an Envelope with a ParameterType which miss the source reference information.

✨ What's your proposed solution?

A simple solution would be to:

• add a SourceReference in the io.cucumber.messages.types.ParameterType. Hint: requires changing the cucumber messages schema (https://github.com/cucumber/messages/tree/main/jsonschema) which generates classes for Java and other languages, see Add the SourceReference in ParameterType messages#145. A snapshot version of the library should be made.
• fill the ParameterType source reference when the Envelope.parameterType "event" is sent to the event bus, see Add source reference on Envelope.parameterType cucumber-jvm#2719 for the corresponding Java feature.
