meta: move Trott to TSC regular member

At the current time, I'm not able to give Node.js the time and attention
it needs and deserves from a voting TSC member. I'm proud of the work
and efforts I've made as a TSC voting member, and I want to leave before
I'm less happy with my efforts. Thanks for all the trust and good will
over the years.
