title: Single quote in tsx file with prettier
body: <p>For 2-3 weeks, while I didn't change anything in prettier file, VSC started changing single quotes to double quotes, while it was always single quotes. I tried many options but it keeps changing it. Heres my .prettierrc</p>
  
  <pre><code>{
    "trailingComma": "es5",
    "printWidth": 200,
    "semi": true,
    "singleQuote": true,
    "jsxSingleQuote": true,
    "tabWidth": 2,
    "quoteProps": "as-needed"
  }
  </code></pre>
  
  <p>EDIT: I think, that it is a matter of .tsx files, as prettier has just option for .jsx files but still didn't find a solution.</p>
