Upgrade TypeScript to v5 in React-scripts

[miguelhormigo]

React-scripts currently relies on TypeScript up to v4, despite the availability of v5 since March. It would greatly benefit developers if the library were also compatible with TypeScript v5, ensuring that those of us already utilizing v5 can avoid any potential dependency conflicts

Are there any plans to move this forward? It's been an issue in one of our projects for a while, and it's looking more and more like we'll have to drop create-react-app.

CRA is pretty much dead. I advise switching to vite. I have done this for a few projects, and it is really straight forward.

See #13289 for reference.

despite two at least two PRs still not resolved. I second @jpgoelz view that it might be best to switch to vite. See https://vitejs.dev/ for more details.
