Feature: Github source control integration: Ensure limited permissions

[JorgeAtPaladin]

For now when I connect a github for the source control integration, this is the permission view I get.

Once I press the green authorize button, the window closes and the app is authorized as can be seen in my settings:

It is unclear what Act on your behalf means, permissions wise.

But for other applications, they do not need to be globally connected to my account, instead they are just connected to specific repositories.

Update: I could still sync fine after removing the global app configuration, and only keeping the repo specific one.
