Get Bids from Backend API

[PercyODI]

Story

As a consumer of the backend API, I want to get all bids So that the Frontend can start to display them

---

Notes:

• This should be a new method on the bids controller
• Expected endpoint should be GET http://localhost:15665/api/bids
• See the ERD Diagram at https://github.com/PercyODI/Stage2.PieAuction/blob/master/Instruction.Images/ERD.jpg for what bids should look like
