Bump to 0.2.1:1

Wrapper-only revision: the images are unchanged from 0.2.1:0, so only the
downstream digit moves. Release notes now describe this revision (rebuilt
against start-sdk 2.0.9, requires StartOS 0.4.0-beta.10) instead of 0.2.1:0's
image bumps.

The version file moves to versions/current.ts, where the guide keeps the latest
version — a dated file is only for a released version that carries a migration,
and this bump carries none. No `other` entry is needed: the version graph
synthesizes a range beneath current, and the packed manifest derives
canMigrateFrom <=0.2.1:1.
