## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This PR fixes #20811 , current approach reverses the order in `BtreeSet`
however as pointed in
https://github.com/astral-sh/ruff/issues/20811#issuecomment-3398958832
here we cannot use I`IndexSet` to preserve config order since Settings
derives `CacheKey` which isn't implemented for `IndexSet`, another
approach to preserve the original order might be to use `Vec` however
lookup time complexity might get affected as a result.
<!-- How was it tested? -->
I have tested it locally its working as expected ,
