doc: move @Fishrock123 to TSC Emeriti

It was a good run. Almost 5 years.

I haven't really been involved in the last 3+? months though,
so it's time I call it and 'retire'.

I think it is unlikely that I'll be on the TSC again,
as node is unfortunately becoming increasingly
disinteresting (& frustrating) to me.

(So long and thanks for all the fish!)
