Upcoming API changes in styled-components v4

[quantizor]

Just a heads-up that we will be making some top-level API changes in v4 that may affect your library.

1. injectGlobal is being removed
2. createGlobalStyle is being added

createGlobalStyle can likely inherit any syntax highlighting rules you may have been using for injectGlobal, styled.* etc.

More info: styled-components/styled-components#1867

It would be great to get syntax highlighting for createGlobalStyle. For now styled.createGlobalStyle`` supports syntax highlighting but doesn't work since I can't seem to inject my global css variables using the default import.
Using the named import const { createGlobalStyle } works as intended but doesn't seem to have syntax highlighting.

I think you can probably just add createGlobalStyle to the pipe list at the end of this with the other helpers like keyframes and css: https://github.com/styled-components/vscode-styled-components/blob/master/syntaxes/styled-components.json#L7

I think with #130 and #129 we're good here.
