fix: stop requiring com.lihaoyi libraries for schema generation

Instead of requiring the project to load the com.lihaoyi.upickle
and com.lihaoyi.os-lib libraries in the project, we now dynamically
add them to the dependencies when running the schema generation command.

It still not bulletproof as it could lead to version conflict with
existing libraries but it will good enough for now :-)
