Connectivity test: add an Indonesia country list

We ship country-focused connectivity lists (Iran, Russia, China, Brazil, India…) so people can quickly check which services matter for that country. Indonesia is one of the world's largest internet markets and we have nothing for it — if you're familiar with the Indonesian internet, you know better than we do which sites matter.

Same recipe as #405: id: 'indonesia', emoji , ≥10 members mixing global services relevant locally with major Indonesian platforms (e.g. Tokopedia, Gojek, Traveloka, Bukalapak, Kompas…), names in every full locale pack (en, zh, fr, pt-BR, ru), favicons committed via pnpm fetch-favicons.

pnpm check green; comment to claim; PR targets dev.
