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 this source reference field with the Java method similarly to what is done in io.cucumber.messages.types.StepDefinition (in this case: based on the io.cucumber.cucumberexpressions.ParameterType which contains the Java Method). Hint: the cucumber messages snapshot library should be used in the PR
• Create an issue in each supported language repo (ruby, js) : done, see mentions in the issue history below.

⛏ Have you considered any alternatives or workarounds?

The ParameterType can be obtained by looking at all methods annotated @ParameterType on all classes of the classpath, but this is not really efficient.

Seems acceptable. The message protocol must be updated to include this information. Messages are generated from a schema definition in https://github.com/cucumber/messages.
