VSCode syntax highlighting : Dimming `end`s

[pfitzseb]

So for e.g. One Dark Pro you’d add

    "editor.tokenColorCustomizations": {
        "textMateRules": [
            {
                "scope": "keyword.control.end.julia",
                "settings": {
                    "foreground": "#834d94"
                }
            }
        ]
    },

to your settings.json.
