Consolidate search bars

[david-gonzalez-a8c]

Description

The search bar in "Bookmarks" looks oddly different from the other ones in the app like the one in "Podcasts", "Discover" or "Listening history". Can we please consolidate these?

Step-by-step reproduction instructions

1. Go to "Profile" and "Bookmarks"
2. Compare the search bar to the ones found in "Podcasts", "Discover" or "Listening history"

I think the differences are due to two different UI technologies being used (UIKit and SwiftUI). Not sure if they can be exactly the same.
