Enhancement : Show type name on node root when possible

[TonyGravagno]

These screenshots will immedaitely clarify the request. Note mouseover on config reveals the type to be AppConfigJson. Yes, the treeview shows the typename on mouseover but if there is a type, can we have an option to see it in the tree without mouseover?

As another example, note this code and then see how the tree shows it:

type ReactStyles = Record<StyleKeys, CSS.Properties>
type MuiStyles = Record<StyleKeys, CSS.Properties>
...
  styles: {
    current: () => ReactStyles
    react: ReactStyles
    mui: MuiStyles
  }

There is plenty of room there to show "Properties (ReactStyles)".

Thanks!
