[council] GNSO Chair Handbook

Dear councilors, The attached GNSO Chair Handbook has been developed in collaboration with the current and past GNSO Council leadership, to facilitate the handover between leadership teams, with an emphasis on the role of Chair. It will be posted on the GNSO website<https://gnso.icann.org/en/council/procedures> shortly, but it may be of interest as well to those who want to better understand the role and responsibilities of the Council leadership. Thank you, Nathalie
