Expose LocaleInputType in exported GraphQL schema

[ghost]

Hi 👋🏻

It could be cool to add LocaleInputType to the generated schema when you do payload generate:graphQLSchema, this way it would let us create strongly typed queries on front-end using GraphQL codegen.
It could be amazing to add locales as an enum within the schema too.

What do you think about it?

Erratum, LocaleInputType is already exported from schema made a mistake on my side 🤡

How would you reference this in a custom graphql endpoint definition?

Figured this out:
locale: { type: payload.types.localeInputType },
