project.config: grant Commit-Queue+1 access to gobot

The gobot account needs to be able to start trybots on CLs it generates
and mails. This can be implemented in multiple equivalent ways, and for
the previous trybots it was a separate Run-TryBot+1 vote permission:

	 label-Run-TryBot = +0..+1 group cria/project-golang-may-start-trybots
	 label-Run-TryBot = +0..+1 group gobot

It was initially added to the may-start-trybots cria group for leaving
Commit-Queue+1 votes needed for the new LUCI trybots, and this CL adds
it as a separate permission here to restore consistency:

	 label-Commit-Queue = +0..+1 group cria/project-golang-may-start-trybots
	+label-Commit-Queue = +0..+1 group gobot
