The coins_per_utxo_size parameter should be used instead of min_utxo for Alonzo and later

[katomm]

Hello, I was playing around with Yaci DevKit and Evolution SDK and noticed that the Blockfrost provider's protocol parameters schema requires min_utxo as a mandatory field.

Reproduction

import { createClient } from "@evolution-sdk/evolution";

 // Yaci DevKit running locally (yaci-devkit up --enable-yaci-store)
 const client = createClient({
   network: "preprod",
   provider: { type: "blockfrost", baseUrl: "http://localhost:8080/api/v1" },
   wallet: { type: "seed", mnemonic: "your twelve word mnemonic phrase here ..." },
 });

// This throws:
await client.getProtocolParameters();

Error

ProviderError: Blockfrost getProtocolParameters failed
  └─ ["min_utxo"]
     └─ is missing

{
  "min_fee_a": 44,
  "min_fee_b": 155381,
  "pool_deposit": "500000000",
  "key_deposit": "2000000",
  "coins_per_utxo_size": "4310",
  "max_tx_size": 16384,
  "max_block_size": 90112
}

(coins_per_utxo_size is present, min_utxo is not)
