For some reason the tests are not passing on Appveyor's Windows platform:

Perhaps #5604 will fix this

#5604 didn't solve it.. I've assigned to @pieh to take a look 🙏

So types.ComponentProp[0].doclets looks like this in windows - it doesn't remove \r which is part of default windows endline (\r\n):

@jquense what's the best place to fix this (I'm not familiar with gatsby-transformer-react-docgen)
