Source change required for JsonDocument

[wernerpaulin]

When changing to JsonDocument, I had to change the code to iterate over the json configs:
JsonArray configurations = doc["Configurations"].as();
if (configurations.size() == 0) {
return NO_UPDATE_PROFILE_FOUND;
}

    // Step through the configurations looking for a match
    for (JsonObject config : configurations)
    {
        String CBoard = config["Board"].isNull() ? "" : String((const char *)config["Board"]);
        String CDevice = config["Device"].isNull() ? "" : String((const char *)config["Device"]);
        CVersion = config["Version"].isNull() ? "" : String((const char *)config["Version"]);
        String CConfig = config["Config"].isNull() ? "" : String((const char *)config["Config"]);

        if ((CBoard.isEmpty() || CBoard == BoardName) &&
            (CDevice.isEmpty() || CDevice == DeviceName) &&
            (CConfig.isEmpty() || CConfig == ConfigName))
        {
            if (CVersion.isEmpty() || CVersion > String(CurrentVersion) ||
                (DowngradesAllowed && CVersion != String(CurrentVersion)))
                return Action == DONT_DO_UPDATE ? UPDATE_AVAILABLE : DoOTAUpdate(config["URL"], Action);
            foundProfile = true;
        }
    }
    return foundProfile ? NO_UPDATE_AVAILABLE : NO_UPDATE_PROFILE_FOUND;
