github: milestone labels m1 to m8 and later; phase labels are history

Adds the labels m1 to m8 and later, with neutral descriptions. The phase
labels stay, and their descriptions say they are historical. The
bootstrap script never edits an existing label, so the new descriptions
reach a repository only when its labels are created. The CHANGELOG entry
for Plan v1 is added under Unreleased.
