Instead of creating a set, technically it's already [sorted](https://github.com/llvm/llvm-project/blob/main/clang-tools-extra/clang-tidy/ClangTidy.cpp#L484), but for clarity, and not to depend on something implicit, we could change the `vector<string>` to be a `StringSet` from the [start](https://github.com/llvm/llvm-project/blob/main/clang-tools-extra/clang-tidy/ClangTidy.cpp#L470). (Didn't check all dependencies on this value yet)
