Use $rawModelDataInput as construct function parameter name in Model.phptpl

Because when Symfony deserializer the object will not find the parameter value in the saved data and use the default parameter value(empty array).

Then the model construct function will get error: `Typed property must not be accessed before initialization` since PHP 7.4
