Playwright docs

[aaronhans]

Working on some playwright docs with @zakiya

They playwright.md is the start of a playbook recording some info useful for writing end to end tests with playwright

The package.json and corresponding test files are there to run the samples

[aaronhans]

No, not real tests

These are docs on testing

This is internal facing documentation that is convenient to write and consume in github repo markdown. @zakiya and I thought it worked well here but happy to move it if we have a better location

Capturing some notes here for future documentation:

• playwright.config.js is pretty useful. We should document and/or reference it. headless: true/false can take the place of PWDEBUG = 1
• Users need to be aware of the Page.Locator class
• You can store tests somewhere besides tests folder by using playwright test my/chosen/path/menus.spec.js commnad
