Clarify Studio versions to be used in tutorials

[dvojtise]

The various tutorials referenced on http://gemoc.org/tutorial.html (or other places in the documentation) have not been updated with the latest version of the studio (neither for the last stable nor for the master branch)

We need to clarify which tutorials have been written for/verified/updated with a given version of the Studio

Additionally, the tutorial page should reorder them according to the target studio version (most recent first)

The DIY section of the official examples (for example https://download.eclipse.org/gemoc/docs/nightly/K3FSM-example.html#K3FSM-example-DIY) can also be referenced in the tutorial pages
