ChatByUsername queries by ID, not by username

[zewebdev1337]

bot.ChatByUsername queries the API with the chat_id instead of username, not sure what happened there because I see the function defined above (ChatByID), converts its int64 ID to a string and then calls ChatByUsername with it.

After checking the official API documentation it seems like we can only query users by ID, it might seem ambiguous as it mentions usernames too but only for channels and supergroups...

From the official API docs:

getChat

Use this method to get up-to-date information about the chat. Returns a ChatFullInfo object on success.

Parameter	Type	Required	Description
chat_id	Integer or String	Yes	Unique identifier for the target chat or username of the target supergroup or channel (in the format @channelusername)

For my usecase, I wanted to query users by username, not channels or supergroups.

However I'm going to try to query it with a username since it's not rare for docs to go out of date, especially for such a big project as the Telegram bot API. If I succeed I'll report it here and contribute by making the necessary changes, however if I don't succeed I'll just close this as not planned.
