[clang-tools-extra] [clang-doc][NFC] clean unused variable in HTML generator (PR #135505)

[Mohamed Emad via cfe-commits]

https://github.com/hulxv created https://github.com/llvm/llvm-project/pull/135505

While reading the code, I found some dead variables that are not used anymore but it still declared without removing them. I think it should be removed.
