Create a Playground for Paycrest using Bonadocs

User Story
As a developer, I want to interact with paycrest's gateway contract and APIs. Bonadocs playground allows us have a single environment to enable intuitive interaction.

Acceptance Criteria

1. GIVEN the API endpoints in our docs api.md
   WHEN trying to query certain information i.e fetch exchange rates
   THEN create bonadocs actions that query the endpoints with fetch API in javascript. Also add
   Sample:

2. GIVEN the gateway contract
   WHEN trying to create orders
   THEN create a bonadocs action that interacts with the API and gateway contract to create an order

3. GIVEN the sender API
   WHEN external apps want to enable off ramp
   THEN initiate an order using the sender API
