Update customize.html (#1408)

For this customization to work, need to add more partial scss files as above
$addColors: (
  "twitter":($twitter, $twitter-invert),
  "linkedin": ($linkedin, $linkedin-invert),
  "github": ($github, $github-invert)
)
$colors: map-merge($colors, $addColors)

Otherwise it failed in my sass build
