Describe the feature

It'd be nice to get access to the very basics of the i18n config in nitro.
Just to give a simple example, we're trying to verify a language passed in query params is actually supported by our website. Or load/return data for every possible locale.

There's of course the option to hardcode/copy it, however I think it'd be preferable to be able to pull i18n related configs straight from the source - similar to what useI18n().locales provides.
