Incorrect return annotation on `queryLiquidationQueueBidPoolsByCollateral`

Currently:

```ts
interface Option {
lcd: LCDClient;
collateral_token: string;
start_after: number | undefined;
limit: number | undefined;
}
export interface BidPoolResponse {
sum_snapshot: string;
product_snapshot: string;
total_bid_amount: string;
premium_rate: string;
current_epoch: string;
current_scale: string;
}
export declare const queryLiquidationQueueBidPoolsByCollateral: ({ lcd, collateral_token, start_after, limit }: Option) => (addressProvider: AddressProvider) => Promise;
```

The return type of `queryLiquidationQueueBidPoolsByCollateral` should be:

```ts
export interface BidPoolsByCollateralResponse {
bid_pools: BidPoolResponse[]
}
```

Version:

```
"@anchor-protocol/anchor.js": "^5.0.2"
```

Documentation: https://docs.anchorprotocol.com/smart-contracts/liquidations/liquidation-queue-contract#bidpoolsbycollateralresponse

Example response in documentation:

```
{
"bid_pools": [
{
"sum_snapshot": "1.0",
"product_snapshot": "1.0",
"total_bid_amount": "1000000",
"premium_rate": "0.1",
"current_epoch": "0",
"current_scale": "0"
},
{
"sum_snapshot": "1.0",
"product_snapshot": "1.0",
"total_bid_amount": "2000000",
"premium_rate": "0.2",
"current_epoch": "0",
"current_scale": "0"
}
]
}
```

Start at the TypeScript declaration for queryLiquidationQueueBidPoolsByCollateral and compare its return shape with the BidPoolsByCollateralResponse shown in the issue and the linked liquidation-queue documentation. Update the annotation so it represents the documented bid_pools wrapper, then verify the generated declaration matches the example response.
