Remove jquery-ui-bundle and use vanilla js instead

[mustaphaturhan]

Closes #181

🛠️ Fixes Issue

While we want migrate the project to vite and modern development stack, one of the blocker was jQuery. To handle jQuery in vite, we have to use plugins like rollup-plugin-inject. But why would we need what when we can solve the problem at its root?

This PR closes #181 and removes the jQuery.

👨‍💻 Changes proposed

• Removes jquery-ui-bundle and jQuery
• Updates the parserOptions of eslint since we are using modern features of ecmascript.

📄 Note to reviewers

• I updated to "ecmaVersion": 2022 because we are using **?.** syntax in the project.

ping @nilsnolde @chrstnbwnkl, it could be nice if we can merge this and #244

Definitely, I'll build and run it later today. I don't have much to add on logical review, I'll just do some UX playing around.

Thanks for doing this! The only tiny little thing I found was: if the left panel is closed while the height graph is open that graph closes, where on master it doesn't. On master it tries to (not very successfully) resize instead.

Anyways, not in any way a blocker IMO.
