[llvm] [.gitignore] Ignore .claude and .gemini in subdirectories (PR #167029)

[Jonas Devlieghere via llvm-commits]

https://github.com/JDevlieghere created https://github.com/llvm/llvm-project/pull/167029

Currently `.claude/` and `.gemini/` are only ignored in the root of the repo. Developers might conceivable run these tools in project subdirectories, in which case these should be ignored as well.
