introduce `useSendReaction` hook. This hook will eventually be used in the following files
# `native/chat/text-message-tooltip-button.react`
# `native/chat/multimedia-message-tooltip-button.react`
# `native/chat/robotext-message-tooltip-button.react`.
This hook will also eventually replace `onPressReact` and `sendReaction` in `reaction-message-utils`; however, it is not safe to remove it yet because the like button in the tooltip still calls these functions, but we will address this in a subsequent diff
