Description

this applies to all Task Forces. they are listed in https://www.w3.org/WAI/about/groups/

this was confirmed by Comm and SysTeam in July 2025: https://lists.w3.org/Archives/Team/w3t-comm/2025Jul/0195.html

maybe there is a PR to make this change? maybe it is combined with other changes that need more consideration? if so, please split the PR so we address this change that needs no other review.

to be clear: Shawn approves the change in Task Force pages from "Chairs" to "Facilitators".

Thanks!
