Using defineI18nLocaleDetector, event.context.i18n?.locale could be async function instead of string

[DavidDeSloovere]

Describe the feature

event.context.i18n?.locale is typed as string I use a custom defineI18nLocaleDetector, and the actual type of locale on the context is function (it's value is [Function: bound localeDetector] AsyncFunction)

Would it be possible to change the typing?
