Suggestion theme improvement

[yuritoledo]

This options to widget/suggestion is good too:

    "workbench.colorCustomizations": {
        "editorSuggestWidget.background": "#161130",
        "editorHoverWidget.background": "#161130",
        "editorSuggestWidget.selectedBackground": "#0C0A20",
        "editorSuggestWidget.border": "#0C0A20",
        "editor.lineHighlightBackground": "#0C0A20",
    },

And this turquoise in functions:

 "editor.tokenColorCustomizations": {
        "[Outrun Night]": {
            "functions": "#00FFF1"
        }
    },

I can PR if you accept ;)
