No beta label for CS on SM in 16.7

What does this MR do and why?

Do what this MR - !139965 (merged) - does, but updates the correct view that is shown to 16.7 users.
In the original MR, the updated view is behind the FF until 16.8 - so for 16.7 the original MR is no-op which is not the intent, it seems.

⚠ This is a new requirement for Cloud Connector. What we agreed on previously is discussed in that issue description, plus this edit from Katie (which simplifies things a bit and avoids some additional logic). This MR changes the original intent.

Please involve Legal/Design or other interested parties if needed. As with any last-minute change, it may be risky if not communicated well.

@tmccaslin executive team requested this change and legal approved it.

Note that if will not merge this MR into 16.7, there is no need to use it, because the entire view affected by this MR will be dropped in %16.8: !139141 (merged)
