ci(wasm): check wasm32-wasip1-threads build (oxc-project#9569)

Duplicate of oxc-project#9555, but just stacked on top of oxc-project#9566.

`napi-rs` for some reason omits the `export * from '@oxc-project/types';` line from `index.d.ts` when building for WASM.

I don't know how to fix that, so added a hacky script to fix up `index.d.ts` manually. This is not at all ideal, but at least it now compiles and CI passes.
