[Feat] do not focus output window on sync

[jasonswearingen]

💡 Is your feature request related to a problem? Please describe.

Noticed this when enabled this Settings Sync extension and the vs builtin settings sync.
When they are both on, there seems to be a conflict with the Settings Sync extension and VSCode's built-in settings sync colliding. When that happens the Settings Sync extension thinks there are changes at every startup.

This "changes ocured" causes a very annoying behavior: the output --> Code Settings Sync pane from being focused upon every vscode startup (maybe it is really "upon settings sync performing an action", but that occurs on startup)

💡 Describe the solution you'd like
probably don't need to worry about the re-upload (let it happen) just dont' focus the output window on upload

💡 Additional context
I originally thought this was a problem with the VSCode builtin. see: microsoft/vscode#107245

@jasonswearingen I was having the same issue and it was getting really annoying. I think this is the setting that stops it:

{ "sync.quietSync": true, }

Why quietSync isn't the default is beyond me. Nobody wants SettingsSync to constantly steal focus.

All of my sync settings in the JSON file are greyed out as unknown config settings. The output tab launching on every vscode start is really annoying, what am I missing?
