PublicTickerData is a list in Bybit API, but declared as an single object

[TheLeBot]

In official API despription we see data for the Ticker Bybit WebSocket API as an array. Despite that the current implementation uses PublishTickerData container which is not a List or Array. This way we will have problems if one response on WebSocket will bring more then one data.
It would be more correct to use a list same as for Klines.
