Code-settings-sync: [Feat] do not focus output window on sync

💡 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: https://github.com/microsoft/vscode/issues/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.
