06 upgraded react-scripts to v5

[RaniAgus]

I'm using WSL2 to follow the course, and there was an issue with this example project: auto-reload didn't work. It was throwing this error every time I updated a file and stopped responding:

VM256:2 Uncaught ReferenceError: process is not defined

I solved it by upgrading react-scripts to v5.0.1 😄
