build: Initialize necessary modules

[JSMonk]

Hey @whitescent We discussed that the repo will be a monorepo with 3 Gradle submodules:

• Gradle plugin
• Library for describing stories
• Gallery

Could you make this generated by the wizard project as a Gallary submodule? We also need to create two more: for the Gradle plugin and for the library.

As a reference, you could take a look at the Koin repository

oh that's my fault, I forgot to add other modules, Now they are added to the project :)

The project structure now looks like:

The Gralde Plugin Module is only include jvm dependency

And the runtime module is treated as a multi-platform supported module. How does it look now? 🧐
