(Small) Store Screenshots Update 📱

Few months ago, we updated the store screenshots to be consistent with the new app look.

I was a small project. The goal was only to update the old UIs displayed in screenshots. It wasn't the time to change the strategy, the content, or the design.

But I took the opportunity to refresh — a little — the design (new text style, new background, screen frame, and some other details ✨).
