Trading account, GetAccountConfigurationAsync Error

[MihailRom]

Hello!
Please, fix same values in OkxAccountConfiguration model class
https://github.com/burakoner/OKX.Api/blob/master/OKX.Api/Models/TradingAccount/OkxAccountConfiguration.cs

Properties
public OkxAccountRoleType? AccountRoleType { get; set; }
and
public OkxSpotCopyTradingRole? SpotCopyTradingRole { get; set; }
have similar value [JsonProperty("roleType")]

So, method GetAccountConfigurationAsync returns an error

I've fixed this issue. Please check out Version 1.5.6 at f8b6ccc and https://www.nuget.org/packages/OKX.Api/1.5.6

Thank you for feedback. Have a great day.
