Our E2E tests are in a very messy state right now. Due to a pile of hacks that accumulated over months, it's very hard to understand what's happening to the packages.
I want to simplify this. As a first step I want to get rid of this variable.
It looks like it's not actually being used. (The branch is always false.) And since Yarn now ships with CI images, we actually do use Yarn on CI already.
With this change, we're just eliminating already dead code. Next, I'll try to simplify the actual CI script, but for now I just want the code to reflect what it actually does because it wasn't obvious.
