docs: addMetamaskNetwork description made clearer

Great work with this library :)

While using it, I noticed that the documentation of addMetamaskNetwork could've been a little bit clearer - this method not only adds a new network but also switches to it in the process.
Ideally, this method should also be named just like you've named 'allowMetamaskToAddAndSwitchNetwork' which clearly tells what the function would do.
