install / run arduino ide on ubuntu 22.04

 The raw arduino downloads from the .cc website didn't seem to run.

 There is no install included, just a full running appimage and a zip of the application to download.

the version installed by using apt is of the 1.8, version, very old.  It does run however.  

It does solve something when run.  There is a permission that has to be added, and the app prompts for it.  

Other problem is that xapp library is missing.  That is in the console scroll when you run the app 

the AppImage seems to run once made executable.  It seems to also install the libs once run. 

 There was a complaint  when running the AppImage about xapp library component missing.  W/o installing it the gui doesn't finish running.
