Create an infrastructure for E2E tests

[baruchiro]

We want to run End to End tests by running a browser instance, installing the extension, and clicking on the page to see the extension in action.

The requirements:

• Run a real browser
• Install the extension
• Run on headless mode
• Run with a real URL (or do you have another suggestion?)

Cypress

Currently can't visit StackOverflow.

Selenium

Headless Chrome can't load extensions.

Playwright

Managed to run Chrome with an extension, but the solution for headless didn't work.
Firefox extension is not supported.

I can try to use Playwright I have some experience with it. not with extensions but I think they have some sort of solution for it.

[baruchiro]

@ETtestim Yes, please! I will appreciate it.

Please see the updated first message here, I listed the requirements.

@ETtestim implemented it with Playwright and Chrome, works in headless mode.
