doc: move 8 collaborators to emeriti

As discussed in TSC email, I contacted 8 Collaborators whose last
activity appears to be quite some time ago to suggest that they be moved
to emeritus status until such a time as they will be active again. There
were no objections from the 8 Collaborators or the TSC.
