Fetch gas price using low-level RPC method

Alternatively, it can be implemented by extending the JsonRpcProvider class like following:

// eslint-disable-next-line functional/no-classes
export class LegacyGasPriceRpcProvider extends ethers.JsonRpcProvider {
  public async getGasPrice(): Promise<bigint> {
    const value = await this.send('eth_gasPrice', []);

    return getBigInt(value);
  }
}

I didn't prefer this approach because it would necessitate modifying nearly every file that references ethers.JsonRpcProvider, both as a class and as an interface.
