[verifier] fails to work in NodeJS

[remyroy]

@gitcoinco/passport-sdk-verifier fails to work under NodeJS because of the @spruceid/didkit-wasm dependency. According to the documentation on https://www.npmjs.com/package/@spruceid/didkit-wasm-node, you need to use the @spruceid/didkit-wasm-node package instead.

I was getting this error message when I tried:

$ yarn run test
/home/remyroy/Projects/ethstaker-discord-bot/.yarn/cache/@spruceid-didkit-wasm-npm-0.2.1-1bec27787d-53d5fb9ab0.zip/node_modules/@spruceid/didkit-wasm/didkit_wasm.js:1
import * as wasm from "./didkit_wasm_bg.wasm";
^^^^^^

I did some tests in my own fork on https://github.com/remyroy/passport-sdk/tree/nodejs-fix and it fixed my issues when running under NodeJS.

To make this reliable and working in both NodeJS and the browser, it might be needed to polyfill the path and fs packages if you want to depend on that @spruceid/didkit-wasm-node package.

Hello. Thanks for the input. I think we should also add an example for how to use the SDKs on node, to avoid other users having this issue.
We'll look into your fix.
