Feature: Playwright executor

[zikani03]

This PR adds a Playwright support to venom to allow users to perform end-to-end/integration Browser tests using Playwright. It uses the playwright-go library to perform the steps.

Steps to execute actions within playwright are called "Actions" and we have several actions supported so far (see the readme).

Some elements that may need further discussion before merging (if this feature is approved) include

• Configuration and handling of timeouts
• Ability to pass options to different actions (currently most actions use the default options playwright-go uses)
• Whether to support running tests with multiple browsers (instead of just one)
