#### Background
The Android and iOS mobile apps have had the saved tab and custom reading lists for many years now. They have had slightly different functions on Android versus iOS, but custom lists have always been shared and synced on the server. This year, the Web team is adding a "Saved" function, and they will support saving articles to one list, and soon after custom lists. We want to make sure that the experience matches across Web and the mobile apps when users simply saves something, and adds it to a custom list.
#### User story
As a Wikipedia reader who organizes articles across the app and Web, I want the feature for grouping saved articles to be the same thing everywhere, so that I can easily recognize and navigate the same feature regardless of which platform I'm on.
#### Requirements
- Rename Reading lists / Reading list to Collections / Collection in all places it appears in the app
- The "Saved" tab stays the same
