Incorrect URL in Additional Resources Section

[mahdi-hsoumi]

Page: Getting Started with React Section: Additional Resources

Issue: In the "Additional Resources" section at the bottom of the page, one of the links intended to direct users to documentation about UI trees in React currently points to the wrong URL.

Current URL: https://react.dev/learn/preserving-and-resetting-state#the-ui-tree Correct URL: https://react.dev/learn/understanding-your-ui-as-a-tree

The link should point to the correct documentation that explains understanding the UI as a tree.

Proposed Fix: Update the URL to the correct link: https://react.dev/learn/understanding-your-ui-as-a-tree

Thank you!
