feat(webpack): remove "minify" option from HTMLWebpackPlugin

These options are already set by default to the same values by HTMLWebpackPlugin:
-  collapseWhitespace
-  keepClosingSlash
-  removeComments
-  removeRedundantAttributes
-  useShortDoctype
-  removeStyleLinkTypeAttributes

The other options shouldn't be necessary since we are relying on loaders and
specific plugins to minify.
