Align directory name for normalize-colors (#40934)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/40934

The previous `packages/normalize-color` directory name could be confusing, given we have previously published a `react-native/normalize-color` package in addition to the current `react-native/normalize-colors`. After this change, the directory name and `package.json` `"name"` field are aligned.
