Error or warning on the `pause` calls

[Nauss]

I recently switched from Spectron to Playwright to test an Electron app and I'm loving the experience so far.

I'm (over?)using the mighty await page.pause() to develop and debug my tests. And of course, I sometimes forget to remove one of these which causes some troubles later.

It would be nice to have the linter optionally produce warnings (or errors) for the pause() calls.

What do you think ?

This feels like something that could be implemented in the core of Playwright test similar to forbidOnly. @mxschmitt Thoughts on this one?

When running the tests headless it should ignore page.pause() calls afaik, regarding adding it to the test-runner, I'd personally prefer it in the eslint plugin instead, because the test-runner is pretty framework/Playwright agnostic and we need to be careful with adding more pw related CLI/config flags there.
