Add basic widget for iOS14

[jorgej-ramos]

Purpose

The purpose of this PR is to quickly and easily obtain the most important information from RadarCOVID, in the form of a Widget for iOS14.

Approach

Obtaining the values directly from the exposure and preferences repositories, the idea is to build a simple widget that provides the basic exposure information and last update date, as well as the status (active or inactive) of RadarCOVID.

Since I do not have access to the original development account, and the entitlements to develop applications of this type are limited, I have created a fictitious group of applications called group.es.gob.radarcovid, which should be changed at will once this PR is approved.

On the other hand, a change has been introduced to create a suite of UserDefaults without using the bundle name. You can see this change in the struct Config, in which a new static property called userDefaultsSuiteName appears.

Black spots

Since translations are automated server-side, texts has been hardcoded. This must be fixed if this feature goes on production.

I made a mistake pulling out the branch for this job and had to rebase with git rebase --onto to isolate this branch. That is why the commit date is not correct.

It would be nice to do

• Create half and full size widgets
• Include translations

Great contribution! As a minor UI concern, I would suggest adhering to Apple's Human Interface Guidelines and changing SwiftUI's Capsule() shape for a ContainterRelativeShape() in the widget view so the corner radii of both views are concentric. Per the guidelines:

Coordinate the corner radius of your content with the corner radius of the widget. To ensure that your content looks good within a widget's rounded corners, use a SwiftUI container to apply the correct corner radius. For developer guidance, see ContainerRelativeShape.

Awesome!
I didn't remember this guideline. Thank you very much for pointing that out, I'll fix it as soon as possible.

It's better now. Thanks @Androp0v
