In create, provide an "about" menu item to reveal the version being used.

Moved from https://github.com/arduino/Arduino/issues/7368

The title says everything.
Why?
because the problem that is reported may be fixed in old releases.

The problem may not be with Arduino Create, but occurs when using it.
It would be helpful to add the Create version for people supporting other
software to know this information.

The situation is that software version occur very quickly, it is hard to know
if the release you are currently using is the same at the one yesterday.

Just a thought.

You can read the client version in the Help menu, Info tab
