Migrate translation workflows to @v0 and the upstream review template (#73)

* Migrate translation workflows to @v0 and the upstream review template

Moves review and rebase off the exact `@v0.16.1` pin onto the floating
`@v0` tag, per the pin policy settled in
QuantEcon/project-translation#9, and replaces the original
`translate setup` review workflow with the upstream template from
action-translation docs/user/tutorials/connect-existing.md.

This was the least-protected review workflow in the estate. It had no
`labeled` trigger, no concurrency group and no `permissions` block, so:

- a sync's `labeled` events started no review at all on that event type,
  and nothing serialised concurrent runs against the same PR;
- v0.17.0's review dedupe deletes superseded comments, which needs
  `pull-requests: write` — absent here, so dedupe could not work.

The pin was also two releases behind. v0.18.0 carries the fix for a
review-mode defect where a model response missing a criterion score
became NaN and rendered as an automatic FAIL on otherwise clean PRs
See QuantEcon/action-translation#102 — this repo is exposed to it today.

The job-level (not workflow-level) concurrency placement is deliberate
and field-verified: the group is entered only after the job's `if` has
passed, so a `labeled` event for 'automated' skips out without
cancelling the in-flight real review.

* Rebase: also match resync/* branches (action-translation v0.18.1)

The rebase workflow only fired for `translation-sync-*` branches, which
the Action's sync mode creates. The CLI's `translate forward --github`
creates `resync/{stem}` branches, so merging one resync PR never
rebased its siblings — during a drift-recovery wave that leaves a stack
of open PRs whose bases go stale with every merge.

Fixed engine-side in action-translation v0.18.1, but the action-side
half is not sufficient on its own: this `if` gates whether the job runs
at all, and it runs before the action does. Both layers must list both
prefixes or the result is a job that never starts.

Brings this file in step with the upstream template as of that release.
