SCM - Expose editor overview ruler colors for diff decorations for staged changes

[iMobCoding]

You introduced diff decorations for staged changes and it's nice. But I can only control secondary (staged) colors in the gutter, for example:

• "editorGutter.addedBackground"
• "editorGutter.addedSecondaryBackground"

I'd like to have that option for the editor overview ruler also. Right now I can only change for example:

• "editorOverviewRuler.addedForeground"

but there is nothing like:

• "editorOverviewRuler.addedSecondaryForeground"
