Logger only works on Node.js

Summary

The logger needs to be able to work in the browser too, because we use it and modules that depend on it (API) in the app.

Steps to reproduce

https://gitlab.com/openstapps/app/-/jobs/248780170 fails because of:

Uncaught ReferenceError: process is not defined
