Improve Cucumber Glue

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

I usually configure the steps in java libraries. And I have no problem to configure it through the typical RunCukeTests class. Indicating my library classpath in the glue section. But it is not possible to do it through the Visual Studio Code extension. Or maybe yes and I don't know how to do it?

### ✨ What's your proposed solution?

Be able to configure the classpath external jars into glue configuration. Like in JUnit classes.

### ⛏ Have you considered any alternatives or workarounds?

Maybe it will also works if we can put the folder from m2 repository (where it's the jar) in glue configuration.

### 📚 Any additional context?

_No response_

Start by tracing how the Visual Studio Code extension reads and applies the glue configuration, then compare it with the classpath behavior described for the RunCukeTests class. Check how external jars or a folder in the m2 repository could be represented, and define done as allowing Java library glue to be configured and used through the extension.
