Should have documentation specific on how to run on ARM64 architecture

[bstrother1]

Putting this in discussion. I think it would help anyone attempting to run Uno on ARM64 to have either a full guide or documentation on how to get Uno to run on that environment. There seems to be a lot of conflicting information, or early tutorials that no longer work. It would be valuable to have a definitive answer on what is needed/recommended to run an Uno dev environment there.
