Adapt icon path removal from core

[NotMyFault]

The change proposed prepares the plugin for the icon path removal from core in the upcoming LTS line. This change affects plugins not using the icon API or relying on paths. Plugins using the API properly in the first place are unaffected by this change.

Could you trigger a release after merging this PR please, giving people a chance to update the plugin before updating to the next LTS version @Tattoo
Thanks in advance!

@NotMyFault ,

Could you elaborate more what you mean by:

Plugins using the API properly in the first place are unaffected by this change.

Should we use some API for icons? We'd initially rather fix this problem that way, if it's the proper way

Currently you are relying on the path of the icon, which is going to be removed in the next LTS version.
The change I proposed moves you to using the proper API, which is unaffected by this change and will display the icon without relying on a static path.
