Update GridPP documentation

[egede]

The Guide at https://www.gridpp.ac.uk/wiki/Guide_to_Ganga needs updating. Not clear how you get editing rights on the Wiki.

I think Andrew McNab Andrew.Mcnab@cern.ch is the maintainer of the gridpp website.

Turns out that this needs updating of the dirac_ui installed in /cvmfs as well. That in turn is pending a problem with 2FA login at CERN.

See https://www.gridpp.ac.uk/wiki/Quick_Guide_to_Dirac for the Dirac ui installation. In the Docker image we use ./dirac-install -r v6r22p15 -i 27 -g v14r1

New version of the dirac_ui has been installed and instructions updated. Waiting for file to be uploded to Twiki by @Andrew-McNab-UK. Attached here in the meantime.

@marianne013 I notice that you have write access to the GridPP wiki pages. Can I get you to update the page https://www.gridpp.ac.uk/wiki/Guide_to_Ganga with the content from https://github.com/ganga-devs/ganga/files/4632609/ganga-gridpp.txt You should simply be able to replace the full text of the page.

I've updated the wiki.
