chore(astro): revert premature 2.0.0 bump

The 2.0.0 version field was committed manually in c7e2564; the
publish-astro workflow runs `npm version <bump>` against current,
so leaving it at 2.0.0 would push to 3.0.0. Revert to 1.2.2 so
the workflow can do its bump=major → 2.0.0 step (mirrors the
1008195 precedent).
