Download new Workstation releases within the app #300
Description
Currently, the application just launches the web browser to download the updater file. Instead of launching a browser, we should download the installer within the app with a progress dialog. This would still download to the user's download directory (macOS/Windows) and we'd allow the user to launch the file when the download is complete. Overall this should behavior similar to what we'd get if we used Sparkle on the macOS.
Acceptance Criteria
- When the user selects download update a progress bar is shown
- File is downloaded to expected downloads directory
- File can be launched directly from the UI
