ship ESM only

[babu-ch]

closes #2101

By the way, is docs/.ja not used?
If so, would you like me to remove it from this PR?
When I grep with cjs, it gets matched

[kazupon]

We want to remove for cjs, but vue-i18n docs have to support v9 - v12.
So, We need to mention for cjs dropping on v12 as important tip.

[kazupon]

Thank you for your contribution!

I have one more favor to ask 🙏
We want to ship vue-i18n dist files as .js, not .mjs.
Let's try to work on it. 😉

Ah, sorry.
docs/.ja is not maintained, so you can remove another PR.

merged the latest
