[Docs]: Add mutation is unreliable and should be avoided

Closes #8147

• This PR updates the documentation to provide a more accurate and technically correct explanation of why state mutation should be avoided in React.
• The previous documentation often used phrases like "not recommended" or suggested mutation was a bad practice. This was misleading for beginners.

Problem:

Multiple sections in the React documentation misleadingly describe state mutation as "not recommended" or something you can "get away with," when the fundamental issue is that mutating state doesn't trigger re renders.

Key Changes:

The language is updated across relevant pages to emphasize the core technical reason for immutability:

• Mutation does not trigger a re-render.
• Replaced vague warnings with strong language like "unreliable," "should be avoided," and "fundamentally prevents re-renders."
• Stresses that immutability is required for state updates to work correctly, not just a preference or best practice.

• src/content/learn/updating-objects-in-state.md
