Fix: --module-name is no longer supported in `create-react-native-m…

…odule` (#440)

* Remove --module-name option from module creation code

The code presented in the docs for creating the NativeModuleSample still
had the --module-name  option, which was renamed to  --package-name  in:
brodybits/create-react-native-module#431

This commit removes this option, as the --package-name is optional and
by default the name will be set as the one used as second parameter.

* Separate `create-react-native-module` as another option

Official React Native instructions use react-native-builder-bob from
Callstack.io company to create the native module project, while the
example presented below it uses other community library.
It is essential to emphasize that these are not the same ways to create
the project.
This commit adds "or" to ensure that the reader will be aware of those
options.
