feat(client): add sendReaction method to the Client

[maxkoryukov]

PR Details

Add sendReaction method to the Client.

Description

The new method created from Message.react, and the original method now calls the new one.

Motivation and Context

With this method it is possible to send reactions to any message, not only to the just received message, or fetched by "load/fetch messages"

How Has This Been Tested

Basically, the code were just moved, so I called both:

• msg.react
• client.sendReaction

and both worked in private/group messages.

Environment

I've tested with [email protected] inside a node:24.11.0-alpine3.22 (linux) docker image.

webVersion: "2.3000.1030417076"

reasonable change, structure based methods should be mostly calling internal Client stuff anyways
