[Android] Add upgrade banner in the FC47 Primary Course card view

[moiz994]

Based on the changes implemented in FC47, the Learn tab has changed to show a primary course card instead of a course list. We need to incorporate the upgrade banner on the primary course card.

Example UI of new upgrade banner below:

Copy of upgrade button should be the same as the current upgrade banner which is "Upgrade to access more features".

@sdaitzman @ekangedx I've seen on the web somewhere that we used the trophy icon for upgrades instead of locks. It also helps us avoid confusion when using lock icons with users.

Let me know if the icon of choice works

Hi @moiz994, thanks for tracking this, I agree this icon change makes sense! In anticipation of updating to that icon, I've added it to our icons on the Unified Components page.

There's an example of the primary course card with that icon in Figma here. I'll also add this to the next mobile design weekly agenda to confirm the decision, since I know some others on that call were interested in changing that icon.
