Update OpenAPI spec file

[embarggo]

Problem Statement

I wanted to use the newer controller properties when creating an account with Stripe.Account.create but currently I get a Dialyzer warning because controller isn't a property for that function call. If we compare the account create operation (operationId PostAccounts) in the spec file for stripity_stripe with the latest official stripe spec file we can see that the controller property exists in the one but not the other.

Solution Brainstorm

I'd be glad to copy just the PostAccounts section from the official spec into this repo's spec file and make a PR, but I'm sure there are other updates to the spec as well that we may want to pull in. Let me know how I can help resolve this.

I don't think this should be marked stale, as the problem still persists
