Supplying Items to a list template does not work (validation errors)

[rozzrr]

Issue Summary

using the nodejs library i expect that when i do the following :

const list_picker : TwilioListPicker = {
body: "bodyText",
button: "buttonText",
items: [{
id : "1",
item : "item_name",
description : "item_descr"
}]
}

        await client.messages.create({
            contentSid : message.templateId,
            from : message.from,
            to : message.to,
            contentVariables : JSON.stringify(list_picker),
        });

this will provide a series of options to the whatsapp user, however this does not an we are met with validation errors

what does work is this:

const list_picker : TwilioListPicker = {
body: "bodyText",
button: "buttonText",
id : "1",
item : "item_name",
description : "item_descr"
}

        await client.messages.create({
            contentSid : message.templateId,
            from : message.from,
            to : message.to,
            contentVariables : JSON.stringify(list_picker),
        });

which then is valid...

so this means we cannot send an array of items, but only a single one.

Steps to Reproduce

1. Set up a list item picker template
2. send a message providing a list of items to pick from in 'items' array
3. notice the errors from the sdk when this happens (even though all params match up to the varibles in the template)

Code Snippet

 //works
 const list_picker : TwilioListPicker = {
                body: "bodyText",
                button: "buttonText",
                id : "1",
                item : "item_name",
                description : "item_descr"
            }

            await client.messages.create({
                contentSid : message.templateId,
                from : message.from,
                to : message.to,
                contentVariables : JSON.stringify(list_picker),
            });



//doesnt work

 const list_picker : TwilioListPicker = {
                body: "bodyText",

                    description : "item_descr"
                }]
            }

            await client.messages.create({
                contentSid : message.templateId,
                from : message.from,
                to : message.to,
                contentVariables : JSON.stringify(list_picker),
