Add better headwind regex for reason/javascript/javascriptreact/typescript/typescriptreact

[petertriho]

This should be a better regex that works with curly braces {} in react jsx (I believe it should work in reason as well?)

Now works with the following:
className="class1 class2"
className='class1 class2'
className={"class1 class2"}
className={'class1 class2'}
className={clsx("class1 class2")}
className={clsx(foo, bar, "class1 class2", bar)}
className={classname(foo, bar, "class1 class2", bar)}
className={anything(foo, bar, "class1 class2", bar)}

Issues:

• Only sorts first string it encounters i.e.only sorts the first string ("class1 class2") in
  className={clsx("class1 class2", foo, bar, "class3 class4", bar)}

Is there any update on this?
