Refactor Nottingham City to pull only one date per bin type

[TurnrDev]

Nottingham City API sometimes give multiple dates for bins, particularly just after collection date. Locally, it makes sense to only use the smallest of these dates as we want the NEXT collection only.

Here's an example API response which is causing the issue:

  "uprn": "200001405145",
  "address": "FLAT 2 3 CAMERON STREET",
  "postcode": "NG5 2HS",

      "collectionDate": "2025-01-07T07:00:00",

    },
    {
