Small documentation inconsistency regarding the style attribute

[MazeChaZer]

In https://github.com/rtfeldman/elm-css/blob/1f3f8f67339c38033f7a9fc878063d4807afb040/src/Html/Styled/Attributes.elm#L29 it says that the style attribute was removed, but it is actually defined further down in the file. The documentation should probably be worded differently.
