Javier Cicchelli 57f4b3c237 [Feature] Open Wikipedia app (#12)
This PR contains the work done to open the *Places* view of the **Wikipedia** app with the screen centered on the coordinates from a selected location in the `LocationsListViewController` view controller.

To give further details about the work done:
- [x] implemented the `wikipediaPlacesURL` property in the `Location+URLs` extension;
- [x] improved the `LocationsListCoordination` protocol and the `LocationsListCoordinator` coordinator to support the opening of the Wikipedia app;
- [x] improved the `LocationsListViewModeling` protocol and the `LocationsListViewModel` view model  to support the opening of the Wikipedia app;
- [x] implemented the "tableView(_: didSelectAt: )" function in the `LocationsListViewController` view controller;
- [x] added the "wikipedia" to the Queried URL schemes in the Info.plist file to support querying to the Wikipedia app;
- [x] improved the naming of some properties and functions in the `LocationsAddCoordination`, `LocationsListCoordination`, and `LocationsListViewModeling` protocols.
