changelog: [duplicate_trait_bonds]: Added [duplicate_trait_bonds] to style

---

Hi, I've noticed that rustc doesn't complain about duplicate trait bonds like where T: Sync + Sync, which is ood to me. I once written such duplicate bonds in development of https://github.com/asterinas/asterinas when I used find & replace tools to refactor code. Therefore I assume someone else could introduce duplicate trait bonds like me.

I am new to clippy development and feel free to suggest anything about this proposal!
