Embeddable sandbox: do not force refresh on updates
I'm using the embedded sandbox in my development environment extensively. It's great, and works offline as long as it's been accessed once in the browser.

## The issue

However, there's nothing more frustrating that opening my browser, navigating to my development server URL where the embedded sandbox is served, typing in my query/mutation/params/headers and the sandbox decides it's time to update, refreshes the entire sandbox and I'm good to start all over again.
On slow internet connections, this may happen very late, to the point where I could have a document almost ready to copy to my app but then it's completely lost.

This is **really** putting me off. I even considered going back to my previous dev tools such as Playground and GraphiQL for this single reason, even though Apollo Studio is better feature-wise in my opinion.

## Suggestions

Instead of forcefully installing and refreshing the entire Studio, would it be possible to have some kind of "update" icon showing up in the sidebar if/when there's an update available, allowing the developer to install it at a convenient time?
Another alternative would be to completely block the UI with a loading screen until Apollo Studio has determined there's no pending update. That way, when the actual Studio UI shows up we can confidently start using it instead of being left here wondering: "did it have time to check updates? Am I good to go or will I lost yet another document as soon as I'll start typing?".

The main issue here is lost time & effort due to having to start over. If you have other ideas that would improve the DX in this direction please share away!
