* Avoid all buildId's that contain "ad"

Looking through the uBlock Origin filter list, it uses regex wildcards to avoid various things with "ad" anywhere in the string. It's a safe bet to just avoid "ad" all together (as opposed to just at the start).

* Use regex (case incensitive) to check for "ad" 

The following cases will set this regex to true:

```
/ad/i.test("somead")
/ad/i.test("someADlksdjf")
/ad/i.test("adlksdjf")
/ad/i.test("ADlksdjf")
```

* Added a check for ad_ in the buildId

* ad_ > ad

Changed release workflow from `resolve` to `resolves`

This adds triggering the PR Stats GitHub Action for a canary release. It compares the latest canary release with the last stable release and posts it as a comment to the commit. 

Related to [create-react-app#5278](https://github.com/facebook/create-react-app/pull/5278#issue-220142150)

Replaces `import()` with `require` only for the testing environment.

Drops user `<script>` tags and shows a warning in AMP mode. Right now they are only dropped in production mode and left in dev mode so the validator shows its warning since it looks like conflicting props log messages are being cleared causing them to not show. 

Closes: #6688 

It appears this workaround sometimes throws a `NS_ERROR_NOT_AVAILABLE` so we add error handling for it

Update tests to setup webdriver stuff in `jest-environment` and re-use one browser session instead of spawning one for each webdriver call to prevent creating too many BrowserStack sessions. 

* Add example with astroturf (Zero runtime CSS-in-JS)

I also removed the copy it had of `runNextCommand`

* with apollo and redux example: Update deps and fix build

* Fix linting errors

* with apollo and redux saga example: Update deps

* Ran lint error fixers

* Fixes errors that occur when commit occurs

* Commit linter fixes

`unfetch` ^4.0.0 is already used by `isomorphic-unfetch` so this simplifies the dependency tree a tiny bit.
