index: use Node's CommonJS JSON loader

- Node natively supports loading JSON via `require()` since 2011, which is a cleaner and easier way to load JSON:

https://nodejs.org/en/blog/release/v0.5.2

- Node's `require()` safely performs regular JSON decode whenever it detects a ".json" file extension, which is what our "detectable.json" filename is using.

- The `createRequire()` API is only necessary because arRPC is not a CommonJS project. However, if the package.json was changed to `"type": "commonjs"` we would be able to remove those two lines to make the code even cleaner, since `require()` would then be available automatically.

- Using `createRequire()` is a completely normal, supported interoperability feature of Node, and is documented here:
