DRAFT: Validate google analytics attributes on pricing modal experiment

Why is this change being made?

This MR is for validating that our data-ga-variant attributes correctly identify the variant being shown to the user when the modal is triggered in the pricing page.

DO NOT DEPLOY THIS MR - we are not running a real experiment on the pricing page.

To QA:

• Visit /pricing?experiment-review-control to view the control variant
• Visit /pricing?experiment-review-test to view the test variant
