Use AI to generate Playwright automated testing for visuals

[jcubic]

I have an idea for a new feature for jQuery Terminal

There were plans for a long time to add automated testing that tests rendering.

We should use LLMs to generate some automated testing with Playwright.

• Create a plan of what should be tested (needs human input)
• Add Playwright tests
• Add to GitHub actions
• Setup Docker for local testing
• Add visual breaking change in a PR to confirm that the test will catch it

To Test:

• spacing below different background (found recently) ervy demo
• Few ANSI ART (also spacing)
• Prism with JavaScript syntax
• Images
  • Spacing of multiple Images
  • Error Image SVG
• Less rendering
  • Larger content
  • Smaller Content
  • Images
  • Error Images
