@colinhacks I just made some adjustments to the French translations and force-pushed on my branch (I am French).

I forgot to mention that I based my translations on https://github.com/aiji42/zod-i18n - big thanks 🙏 to them!

I've used Claude to convert the JSON translation file from zod-i18n to an errorMap (v4) format as Zod requires.
I'm saying this to highlight the fact that I don't want to take credit, but I would be happy to help if you want me to do the same for the other languages!
Thanks for your amazing library, by the way!!

Wow this is amazing! I'll merge this in and probably cherrypick this into main as well. Thanks!

@colinhacks I've made another branch for you to be able to cherry-pick ababol@6dc637d

Those ones are compatible with zod v3.
