Currently our integration tests are our only validation loop. There isn't a playground where we can just test out the end-to-end. We need to put in the infra and update the steps here (https://github.com/dotnet/try/blob/main/Developer-guide.ipynb) to make this easier.

• Improve Playwright screenshots. Some are currently blank and others are cropped so you can't see the output area.
• Automate command line steps to avoid copy/paste in developer guide.
• Make node site UI more intuitive.
