cleaning redundant code

[notanaveragelifter]

What I Did

• Removed the redundant block in createInterpreter that handled the -resource-dir flag, as this logic is already handled in cppinterop.
• Added Emscripten-specific handling to ensure the -resource-dir flag is correctly set to /include for JupyterLite environments.

Why This Is Needed

• The redundant block caused unnecessary duplication and potential logical errors.
• The Emscripten build previously used incorrect paths for the resource directory, which is now fixed.

Testing

• Verified that the -resource-dir flag is correctly handled in both native and Emscripten builds.
