Add "Inheritance Margin" toggle to Editor Margin context menu

[justcla]

Since VS2022, the Inheritance Margin has been added to the editor window. Suggestion from Gaspard Leon raised on Marketplace to add the option to toggle off the Inheritance Margin.

"installed VS 2022 - incensed by large margin on left of code... looked up online - not much good information, found this extension - Very nice, but still much larger margin then VS 2019... found issue a setting called "Show inheritance margin" which is nicely hidden in Text Editor > C# > Advanced at the bottom... this should be in your right-click context menu..."
