Version the documentation to separate content between major versions of AICA Core #371
Description
The AICA System documentation should generally be up to date with the latest information and examples for our various images and packages. Much of the content is "evergreen", explaining core concepts and the growing ecosystem in general terms. However, some of the content is linked very explicitly to a certain version of AICA Core, namely the overview of the AICA Studio user interface and application examples and guides with code snippets and screenshots. For those sections, we wish to provide multiple versions of the content with a version drop-down.
