editMessageText returns bool for inline messages but library always unmarshals into models.Message

[lxlyb]

According to the official Telegram Bot API documentation, editMessageText behaves differently depending on the message type:

• When editing a normal chat message, it returns a Message
• When editing an inline message (using inline_message_id), it returns true (bool)

However, in go-telegram/bot, EditMessageText always attempts to unmarshal the result into models.Message
