Now that tera 1.17.0 supports localization in the date filter through an optional feature date-locale, this feature can be added to zola.
This is non-breaking, and documented in Tera’s documentation. Fixes #1103. The only downside is that it adds approximately 1.3MB to the release binary.
I can make the PR from my fork.
One question: since this requires tera:1.17, should zola depend on tera:1 or tera:1.17?
