temp: reverse stack order of discussions and upsell in sidebar

INF-1893
Description

Discussions activity shows a significant decline this year (1st screenshot). Part of the reason could be decline in daily active users which is why i plotted % of DAUs who interact with discussions (2nd screenshot). But that also gone down since 2023 even though we now have tray and email notifications.

I suspect that certificate preview in sidebar has contributed in this decline. The preview pushes discussions below the scroll line (3rd and 4th screenshots).

But this is just a hypothesis! I want to test this hypothesis but reversing the order of the CTA and discussions (discussions on top) for a few days. This means that users will see discussions on top ONLY on units where discussions is enabled. I want to see the impact on discussions activity and purchase.

Deploy changes on Monday and revert on the following Monday. That should give us 7 days of test data.
