change in clear language and mental health subgroups

I switched mental health and clear language on the subgroups page


   - Thursday, January 5, 2023 Clear Language
   <https://www.w3.org/WAI/GL/task-forces/coga/wiki/Subgroups/WCAG_3_Coordination>
   - Thursday, January 12, 2023 Mental Health
   <https://www.w3.org/WAI/GL/task-forces/coga/wiki/Subgroups/Mental_Health>

Julie is that ok with you? If not we can just cancel next weeks meeting as
Rain and Jennie are unavailable.

All the best

Lisa
