Add the ability to switch delivery channels for installed applications: Beta, Alpha, RC, and etc

For some applications I use pre-release update channels; it would be convenient to be able to select these update channels.

Good idea @Denis11212 ! In future i will work on this feature in a near future 👍

@Denis11212 Could you please clarify the feature that you want? Like now it is sorting the repos with stable + available release but as i got from your request this is like select the stability type for the release so... it is a bit confusing..

[Denis11212]

@rainxchzed for example, there is such an app https://github.com/torlando-tech/columba and it has the newest version is 0.6.1 beta (Pre-release) . And the newest stable is 0.4.2. It would be convenient for each application in the application information card a button where you can select which versions to update the application to. Up to the newest alpha versions, up to beta versions, or exclusively stable releases only.
