title: Make VSCode apply syntax highlighting to .tsx files
body: <p>Trying to start a gatsby+react+typescript project and VSCode will only apply syntax highlighting to the HTML in my .tsx files. The typescript code remains a single color. How do I fix this?</p>
  
  <p>Note: I have no plugins installed at the moment and the highlighting works if the file type is set to .jsx</p>
