Add documentation for setCustomData method

[polishq]

Currently readers might assume that vtexjs.checkout.sendAttachment() can be used to set customData on the orderForm. Please update documentation to include a section on how to set custom data fields on an account and how to use setCustomData to fill the custom fields with data.

First you need to make a new app in your orderform configuration. To do that:

Make a GET request here: https://{{vendor}}.vtexcommercestable.com.br/api/checkout/pvt/configuration/orderForm

Copy the response and change the apps section. Add a new object there

"apps": [
	{
		"fields": [
			"YOUR_FIELD"
		],
		"id": "YOUR_APP"
	}
],

Make a PUT request on the same endpoint with your updated payload.

After that, you can add custom data using the next method from checkout js:

vtexjs.checkout.setCustomData({app: 'YOUR_APP', field: 'YOUR_FIELD', value: 'VALUE_HERE'});

Hope it helps :)
