chore: track action-translation @v0 in the fr sync workflow (#581)

The fr target repo adopted the floating @v0 pin in
QuantEcon/lecture-python-programming.fr#10; this brings the source-side
sync workflow in line so fr syncs pick up v0.17.0 (deterministic
typography on the sync write path, review-comment dedupe) and future
v0.x releases without manual bumps.
