build: update dependencies

I was having a hard time building bunqDesktop due to outdated dependencies. If it's okay to limit the configurations on which bunqDesktop can be built, then it should now be easier to ensure building works on compatible environments.

This PR:

• Updates a few core dependencies to make it work on node.js 12+
• Sets environment restrictions in package.json

Thanks for merging this PR! It's probably a good idea to update more dependencies. Which ones would you like to see updated first? Also, do you mind if I refactor in the Redux Starter Kit? I am trying to fix a few background processing issues and I expect that reducing the amount of boilerplate is going to be a tremendous help.

I'm always open to code to improve the project. I still need to find time to fix the deprecated API endpoints first which I hope I can do next weekend.

Great!

Refactoring Redux probably does involve renaming several actions, but when successful, it should be a lot easier to manage the store with the starter kit. I'll try to figure out what else we need to do (or document?) to make participating easier; hopefully, we can attract more contributors that way to keep the project going.

Thanks for creating bunqDesktop! It has saved me a lot of time.

Yeah I just gotta rewrite the bunqjsclient with the new endpoints which is a breaking change in there, and then rewrite all the actions and reducers in bundesktop afterwards
