Refactor Redux in FileNode.jsx

[Jatin24062005]

Fixes #issue-2042

Changes:
Replaced connect HOC:
Removed mapStateToProps and mapDispatchToProps.

Introduced useSelector and useDispatch hooks for accessing the Redux store and dispatching actions.

Simplified Component Logic:

Directly accessed Redux state using useSelector:

const fileNode = useSelector((state) => state.files.find((file) => file.id === id));
const authenticated = useSelector((state) => state.user.authenticated);

Dispatched actions using useDispatch:

const dispatch = useDispatch();
dispatch(setSelectedFile(id));
Removed Boilerplate Code:

Eliminated the need for connect and higher-order components (HOCs).

Simplified the component export:
export default FileNode;

Thanks for giving this a shot!

This component is a bit tricky to work with! I tried to do a similar change a few months ago (https://github.com/processing/p5.js-web-editor/pull/3289/files), but ultimately has a few errors with it. Based on the attached issue, I think this might be an incomplete solution here since it aims to refactor the components to use Redux-Toolkit. I'm going to close this for now, but please feel free to look into how Redux Toolkit works!

@raclim Thanks for your feedback! I’d love to better understand the expected approach for the Redux Toolkit migration. Would it be helpful if I opened a discussion to align on the best way forward?

Also, if there are specific issues related to this transition that need attention, I’d be happy to help tackle them. Let me know how I can contribute

We do have a few open PRs (3121 - 3127) at the moment that's already started this process and has the attached issue for it, which I think is a good place to start looking as a reference!
