React dev tools keep saying "Unsupported version"

Similar to #620
I do not have react-dev tools installed in my local project and have installed the correct version of react dev tools globally. As mentioned in the comments on the related issue:

> The "Unsupported DevTools backend version" error persists for me, having tried everything listed. The tool seems bent on using react-devtools 4.14.0-d0ec283819 no matter how I try to upgrade to 4.22.1 everywhere for both react-devtools and react-devtools-core. I am working on an Expo project, on a Mac.

I am using react-native-debugger's latest version, on windows.

Start by reproducing the “Unsupported DevTools backend version” error with the reported React DevTools versions 4.14.0-d0ec283819 and 4.22.1 in the React Native Debugger and Expo setup described. Compare how the debugger resolves the global and local packages; done means it uses the intended compatible backend without the error.
