Summary: Hi! I would like to contribute to React Native, and I am just starting out. I forked the repo and found that it has quite a lot of ESLint warnings – many of which were automatically fixable. This PR is simply the result of running `yarn lint --fix` from the root folder. Most changes are removing trailing spaces from comments. Haven't really done any manual testing, since I haven't done any code changes manually. `yarn test` runs fine, `yarn flow` runs fine, `yarn prettier` is satisfied. N/A [INTERNAL][MINOR][] - Fix ESLint warnings Closes https://github.com/facebook/react-native/pull/18047 Differential Revision: D7054948 Pulled By: hramos fbshipit-source-id: d53e692698d1687de5821c3fb5cdb76a5e03b71e
