Remove FB copyright notices from iOS template (#27725)

Summary:
Files that are to be part of the user’s project shouldn’t have FB copyright notices.

There’s [one notice left](https://github.com/facebook/react-native/blob/66601e755fcad10698e61d20878d52194ad0e90c/template/android/app/src/debug/java/com/helloworld/ReactNativeFlipper.java#L2) in the `android` template, which is in a file that doesn’t seem to be intended to be changed by the user and so that seems fine to me.

## Changelog
