Summary:
Adding `xcscheme` files for iOS template back in. They were removed in https://github.com/facebook/react-native/issues/26471 after https://github.com/facebook/react-native/issues/25451. We have reverted the change on `.gitignore`, as this directory is supposed to be in git, but we didn't revert the removed files. Now they are back as well.
You can also see here that the two files are still missing, they got removed on rc.0 and are still missing on rc.3.
