doc: move Fedor to TSC Emeritus

In a conversation Fedor requested that this PR be made. They plan
to continue working on core as a Collaborator. It is this committers
belief that if Fedor would like to join the TSC again in the future
there is no reason that could not be made possible.

Thanks for all the hard work!
