Color setting for support.variable is missing

[peterdanis]

In JS template literals support variables have the same color as strings. For TS setting is there but for JS it is missing.

{
  "name": "[JavaScript] Variables",
  "scope": "source.js support.variable",
  "settings": {
    "foreground": "#D8DEE9"
  }
}

Thanks for your report 👍

I've created PR #51 which improves the string literal characters and the color of the variable properties.
