Support attachments field

[jtjeferreira]

First of all, thanks for this repository, as it allowed me to bootstrap a braze client very quickly.

Problem

I would like to use the field attachments as described here, but the openapi spec does not mention it.

Suggested Solution

I would like to contribute this change as a PR, but I am not sure if I should update the openapi/spec.json file manually, or create a migration. Or is the specification created from the postman collection and the collection just needs updating?

Thanks for opening this issue @jtjeferreira!

Does the Postman collection contain this field? If not, then please create a migration in either postman/migrations/ or openapi/migrations/.

I added a contributing doc. Let me know if you have any questions!
