fix: remove export kernel settings schema json

[echarles]

This removes

export * as KERNEL_SETTINGS_SCHEMA from '../schema/kernel.v0.schema.json';

which does not seem to be needed and fails downstream repos building with the error ...and cannot be used with 'export *'..

@jtpio @bollwyvl https://jupyterlite-pyodide-kernel--47.org.readthedocs.build/en/47/_static/lab/index.html is working fine.

fails downstream repos building with the error ...and cannot be used with 'export *'..

You mean in a downstream repo reusing the extension, but without webpack?

it is failing while loading the node_modules while building with tsc. I am still trying to see why this is happening, and won't be able to link to a reproducer easily. Is that reexport needed?
