Update progress

**Is your feature request related to a problem? Please describe.**
When updating apps with the "Update all" button, there is no indication of the progress of any app and you either have to go to your notifications or into every single app to check the progress.

**Describe the solution you'd like**
Add a simple way of telling the progress of the update, like on the Play Store. A progressbar, spinner or literally anything else that can tell the state (waiting, downloading, waiting for install, installing) and the progress (download progress).
The "Update all" button should also change to "Stop", because there is no point in having it still there.

**Describe alternatives you've considered**
If a spinner or progressbar is not possible, text (Waiting, Downloading 80%, Waiting to start installation, Installing) should also be fine.

**Additional context**
Maybe some inspiration could be taken from the "Updates"
tab in Play Store or Aurora Store.
