docs: updated examples using the outdated reply method

[gekkedev]

Fixes #2198 .

Changes proposed in this pull request

Updated it to no longer feature the deperecated reply() method.

Partially untested.

Question:
What is sendMessageOptions good for? It has a signature similar to sendText (but less strongly typed). Should it be deprecated?

sendText(to: string, content: string, options?: TextMessageOptions): Promise<Message>;
sendMessageOptions(chat: any, content: any, options?: any): Promise<Message>;
