Reenable tests for react-native-doctor

[NickGerleman]

react-native-community/cli#1515 broke all of our tests, including in PR

Until it can be reverted upstream, I've disabled running doctor in our tests, since it is now broken on Windows. 7e94703

Many of our core contributors are taking some much needed vacation throughout December 2021. Thank you for being patient while we relax, recharge, and return to a normal responsiveness in January 2022. In the meantime feel free to continue to pose questions, open issues, and make feature requests - you just may not get a response right away.
