Updated the tutorial according to all the changes up to Toribash 5.60 (230522).
Main changes that you'd probably make use of are the new commands such as INTROFADE / OUTROFADE and tutorial + replay loading by their absolute path.

Please also note that the way of loading your custom tutorials for testing has changed and it now simplified down to a single Tutorials:runTutorial() call.
I've also attached a new version of runTutorial.lua script: Attachment 628384
