fix: generate correct type for arrays of objects (#706)

[SelfDiseased]

Description

Fixes type generation for arrays of objects, including handling of nested arrays.

Example:
Let's assume we have the following JSON:

{
  "OBJECTS_ARRAY": [
    { "instructions": "Please follow the link" },
    {
      "nestedArrayInstructions": [[{ "instructions": "Please try again" }]]
    }
  ]
}

Old generated type:

export type I18nTranslations = {
    "OBJECTS_ARRAY": [
        string,
        string
    ];
};

Generated type after fix:

export type I18nTranslations = {
    "OBJECTS_ARRAY": [
        {
            "instructions": string;
        },
        {
            "nestedArrayInstructions": [
                [
                    {
                        "instructions": string;
                    }
                ]
            ];
        }
    ];
};
