Show a confirmation notification when installing/uninstalling shell commands

Testing #124841

While it's nice that this automatically works in the background, there was no confirmation in the tool that told me whether it succeeded or failed so I had to manually check. It would be nice if there was a toast that confirmed this. Similar to the settings editor that shows this on your first edit:

We are actually in the process of removing that notification: #125083

I intentionally didn't want to show a notification, given this decision tree: #119463 (comment)

🤔 Hmm...I guess in the decision tree, Does the user really need to be alerted? you could make an argument for both sides. My issue is I ran an action and I don't know whether it worked or not and have to go check. So my confidence in it working is really low.

I restored the previous message we used to show for both commands but I am using a modal dialog instead of a notification given it originates from a user action.

I think the decision tree should account for this actually, imho being blocked or not should not be the only criteria for deciding on using notifications vs a dialog. I would add that a dialog should be used when triggered by a user action such as a command and a notification is used when something is triggered from the background.
