Extend support to React 19

[dream-fx]

Problem

react-scrollable-feed doesn't seem to support React 19.

To reproduce

1. Create a blank Next.js project with React 19:

npx create-next-app@latest

2. Install react-scrollable-feed:

npm i react-scrollable-feed
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: test@0.1.0
npm ERR! Found: react@19.0.0
