Included new fields to multiple endpoints

We have added a new field, "details_platform," to the /coins/{id} and /coins/{asset_platform_id}/contract/{contract_address} endpoints responses.

The field contains information about the asset platform, specifically the "decimal_places," providing details on the decimal places associated with the asset platform.

Example of responses:

{
  "id": "arbitrum",
  "symbol": "arb",
  "name": "Arbitrum",
  "web_slug": "arbitrum",
  "asset_platform_id": "arbitrum-one",
  "platforms": {},
  "detail_platforms": {
      "arbitrum-one": { πŸ‘ˆ
      	"decimal_place": 18, πŸ‘ˆ
      	"contract_address": "0x912ce59144191c1204e64559fe8253a0e49e6548" πŸ‘ˆ
      },
      ......
  }, 
   ......
}
