Windows compile

[BumbleB2na]

Bug

On Windows npm start from cmd or powershell will only compile the full app (ie: either YesterTech or ProjectPlanner) to localhost:3000.

Expected result:

It compiles the chosen exercise to localhost:3000

Environment:

Windows 10 with latest updates. Either latest Chrome or latest Edge browser. Latest node.js LTS with latest npm.

Note: I do not have WSL[2] installed as suggested in the Readme.md

Steps to reproduce:

1. open powershell on windows in project directory
2. enter command npm start
3. make choices in terminal that lead to webpack compile of an exercise
4. navigate to localhost:3000 in web browser

or: enter npm start core-v1 1 and enter 1 for 'exercise' or: enter npm start core-v2 1 and enter 1 for 'exercise'

I believe I found a fix that doesn't require WSL. If you give me permission to create a branch and a PR I'll help fix it.

It's best to make a Fork to do a PR. But yea that would be great, thank you
