test: stub navigator so the i18n test runs on Node 20 too

Browse source 
i18n.js sniffs navigator.language at module load. Node has had navigator as a global
only since 21, so the test passed locally on Node 24 and failed in CI on Node 20 with
"navigator is not defined" — a green local run that proved nothing about the version
CI actually uses. Stubbed explicitly, and verified on both 20 and 24 this time.
