[Bug] Does not works with import attributes

[bertho-zero]

This code

import en from "./en.json" with { type: "json" };
import es from "./es.json" with { type: "json" };
import fr from "./fr.json" with { type: "json" };

throws the following error:

import en from "./en.json" with { type: "json" };
                           ^

SyntaxError: Invalid or unexpected token

The type: 'json' attribute is mandatory when importing JSON modules.
