doc: move 5 collaborators to emeritus status

Move 5 Collaborators to emeritus status. These particular five
Collaborators have done some great stuff, but have been relatively
inactive during the last two years or so. (They have been asked via
email if they would like to remain Collaborators or more to Emeritus.
This isn't a suddent thing.)
