fix(onnx): remove ES module type from onnxruntime package.json

The ONNX Runtime build system generates wasm_post_build.js which uses
CommonJS require() syntax. When package.json has "type": "module", Node.js
tries to run this generated file as an ES module, causing:

  ReferenceError: require is not defined in ES module scope

Solution: Remove "type": "module" from package.json. The build scripts
(build.mjs, clean.mjs) are already .mjs files so they'll run as ES modules,
while the generated post-build scripts will run as CommonJS.

Fixes ONNX Runtime WASM build failure.
