DevTools tells Babel to parse the source code using "jsx" and "typescript" plug-ins:
https://github.com/facebook/react/blob/ed6c091fe961a3b95e956ebcefe8f152177b1fb7/packages/react-devtools-extensions/src/parseHookNames.js#L446-L462

This will work for some simple usages of Flow, but syntax may diverge and cause the parsing to fail.

Let's scan the source code for a @flow pragma and pass "flow" instead of "typescript" if one is found.

We should also add tests for both Flow and TypeScript to the test component pool:
