src: update tutorial with correct static methods in ping example

[therealdannzor]

Running the example in a separate project results in errors because of two missing method implementations. This small update makes the ping-pong example work 😄 .

Thanks for testing out the tutorial @therealdannzor and also thanks for preparing a patch!

#1995 has been merged since the last release, allowing calling methods on a Swarm directly. Thus with the next release this will be fixed. I will prepare a release soon to make sure the confusion is removed.

If you link to the current master branch directly, things should compile fine.

Thanks for letting me know and for the quick reply, I wasn't aware of this planned fix. I'll close this then :)
