feat: adds support for carrier open endpoint

CHANGELOG.md

@@ -5,6 +5,7 @@
 - Removes the deprecated, unusable `add_credit_card` function
   - Stripe has disabled the ability to pass plain credit card details over the wire and now requires using [Stripe.js/Elements/Checkout](https://support.stripe.com/questions/card-tokenization-restrictions-using-publishable-keys). Follow the [Decentralized (EasyPost-Manage Billing) Guide](https://docs.easypost.com/guides/get-started-with-forge/easypost-managed-billing-guide#referralcustomer-billing-management) for more details on the new flow to use.
   - Makes `referral_customer.retrieve_easypost_stripe_api_key` public to help facilitate adding credit cards using Stripe.js
+- Adds support for `FedexDefaultAccount`, `GofoWalletAccount`, `UpsDapAccount`, `UniUniWalletAccount`, and `VehoWalletAccount` by properly routing carrier-account create requests to the `/carrier_accounts/open` endpoint.
