Your first snap: Use of icon in snapcraft.yaml is deprecated

[Jamie Bennett]

https://developer.ubuntu.com/en/snappy/build-apps/your-first-snap/

In the last example snapscraft.yaml file icon: icon.png is listed. This has now been deprecated so the tutorial needs updating.

Instead, the github docs state the following:

Snap icon

Providing an icon for your snap is important, even for command-line applications, if for nothing else than discoverability from management interfaces such as store fronts like webdm.

To use an icon to represent the snap, just drop a PNG or SVG in setup/gui named icon.png for the former or icon.svg for the latter such that the (reduced) project tree would look like:

  setup/gui/icon.png
  snapcraft.yaml

or

  setup/gui/icon.svg
  snapcraft.yaml

[Impact]

 * The documentation is outdated and misleading.

 * This doc will end up in developer.ubuntu.com.

[Test Case]

 * N/A.

[Regression Potential]

 * None, just a documentation change.

This is automatically pulled in from snapcraft. It needs to be fixed there.

There is nothing to test here. The documentation was updated, and the developer site is also up-to-date now.

I'm marking the verification as done.

Thanks Chris!
