Update Fing Smartphone tutorial for new UI update

[ImBIOS]

The old tutorial is not relevant for the new UI for beginner to try. I just update it to make it have better experience for completely beginner who wanna try the fing way to find IP of raspberry pi.

@lurch Have done some CE's, now seems OK to me.

Should we be recommending a specific third-party product here? We've mostly removed references to third-parties from the documentation.

oh please don't delete this third-party tutorial. Cause this is helpful for a beginner who had a phone to find the IP.

no need to merge this thing? @lurch @aallan @JamesH65

[lurch]

@ImBIOS We're all very busy with other tasks at the moment.

[JamesH65]

Sounds like we should just remove that section entirely.

In light of #1911 is this PR still relevant? If there is supporting third-party documentation outside of this repo, and there hasn't been much recent progress I'd be inclined to close it?

[aallan]

After consideration, this content will be removed in any case as part of #1911 as we are no longer supporting third-party applications and tools in the official documentaiton. Closing.
