François 39ea1bb9b7 run examples in wasm in CI (#4818)
# Objective

- Run examples in WASM in CI
- Fix #4817 

## Solution

- on feature `bevy_ci_testing`
  - add an extra log message before exiting
  - when building for wasm, read CI config file at compile time
- add a simple [playwright](https://playwright.dev) test script that opens the browser then waits for the success log, and takes a screenshot
- add a CI job that runs the playwright test for Chromium and Firefox on one example (lighting) and save the screenshots
  - Firefox screenshot is good (with some clusters visible)
  - Chromium screenshot is gray, I don't know why but it's logging `GPU stall due to ReadPixels`
  - Webkit is not enabled for now, to revisit once https://bugs.webkit.org/show_bug.cgi?id=234926 is fixed or worked around
- the CI job only runs on bors validation
