Update PDF generator script for tutorials to use new OCPIGUI variable
Task
The tutorial PDF generation script gen-cg-pdfs.sh controls the generation of CLI-only and CLI+GUI PDF versions of the OpenCPI tutorials that are made available on the OpenCPI web site opencpi.gitlab.io.
This script needs to be updated to use the new "OCPIGUI" variable instead of the deprecated "AVGUI" variable when the new "OCPIGUI" variable has been added to the tutorial source documents according to issue #2909 (closed).
Acceptance criteria
The gen-cg-pdfs.sh
script can handle both the new "OCPIGUI" variable and the deprecated "AVGUI" variable, i.e., the tutorial documents don't have to be updated "all at once". See the "Changes" tab for MR !834 (merged).
