Related to #71.

When using an Asset field and selecting an existing asset, the API returns:

"main-image": {
        "_id": "64368f514cbb71ea5f08edf4",
        "path": "\/2023\/04\/12\/875-875-storyblok_ceeddf138cb9b2d3491fe7399a30eb21_uid_64368f519a6da.webp",
        "title": "875-875-storyblok_ceeddf138cb9b2d3491fe7399a30eb21.webp",
        "mime": "image\/webp",
        "type": "image",
        "description": "",

            "#c0936a",
            "#4d3421",

        "_cby": "643685aafcc37886b1028da7",
        "folder": ""
    },

The path provided doesn't even include storage/uploads. It's really missing a full_path property here with http(s)://<domain>/<folder>/storage/uploads/<image_path>.

The /assets/ or /assets/image/ endpoint don't give the full path either.
