Use require.resolve for modules

[greym0uth]

Instead of hard coding the pkg path for the moduleCrates this plugin should use require.resolve to get the location of the wasm-pack bundle files. This is useful for projects that have a static package.json at the root of the crate the defines its entry point with main. It allows for the wasm-pack bundle to live in any directory in the module (i.e dist, lib, pkg, etc.) as well.

I ran into this issue in my project which is lain out like so:

├── README.md
├── package.json
├── packages
│   ├── web
│   └── webgl
│       ├── Cargo.lock
│       ├── Cargo.toml
│       ├── README.md
│       ├── package.json
│       ├── pkg
│       │   ├── webgl.d.ts
│       │   ├── webgl.js
│       │   ├── webgl_bg.d.ts
│       │   └── webgl_bg.wasm
│       └── src
├── pnpm-lock.yaml
└── pnpm-workspace.yaml
