🧟‍♂️ Introducing Playwright Trace & TraceViewer

[Playwright Trace Viewer](https://playwright.dev/python/docs/next/trace-viewer) is a new GUI tool that helps exploring recorded Playwright traces after the script ran. Playwright traces let you examine:
- page DOM before and after each Playwright action
- page rendering before and after each Playwright action
- browse network during script execution

Traces are recorded using the new [`browser_context.tracing`] API:

python
browser = chromium.launch()
context = browser.new_context()

Start tracing before creating / navigating a page.
context.tracing.start(screenshots=True, snapshots=True)

page.goto("https://playwright.dev")

Stop tracing and export it into a zip archive.
context.tracing.stop(path = "trace.zip")


Traces are examined later with the Playwright CLI:


sh
playwright show-trace trace.zip


That will open the following GUI:
