Upgraded testcafe and browserstack provider.

Description

Upgraded testcafe and browserstack provider. The latest version of TestCafe has a bug regarding dynamically added CSPs, so I needed to create a separate testing page with the CSP built into the HTML to work around the issue.

Motivation and Context

We're running into stability issues when running TestCafe tests. I want to make sure we're on the latest release so we have as many of the available fixes before we dig in further and potentially report more issues on TestCafe and the associated BrowserStack provider.
