Filter out SourceControl.Git package from VS Code workspace

[isc-pbarton]

If I use the Git Web UI to download a VS Code workspace to edit code in a namespace, I can view and edit the SourceControl.Git classes that make up Embedded Git. It might reduce confusion if we can filter those out of the workspace view by default.

@isc-pbarton I think the solution here is the web application editing mode / view.

Actually this is pretty easy - can use a filter like:
?filter=*.*,'SourceControl.*
