pagePreviews: Scale A/B test bucket sizes by 10

Currently, we're seeing ~10 Popups events/s at peak time [0]. We've had
the go ahead from Analytics Engineering to increase that rate to ~100
events/s [1]. Since the rate is proportional to the size of the on and
control buckets - controlled by $wgPopupsAnonsExperimentalGroupSize - we
simply multiply it by 10 to achieve the desired rate.
