refactor: migrate from argon2 -> @node-rs/argon2 (#4733)

* chore(deps): replace argon2 w/@node-rs/argon2

* refactor: clean up hashPassword functions

* refactor(util): pass in process.platform

* fix: use correct settings for test-extension

Before, it was running into errors with an @types package.

Now, we're correctly running `tsc` so it picks up our `tsconfig.json` and we're
telling TypeScript to not typecheck our lib and exclude `node_modules`
