[clang-tools-extra] clang-doc switched from using relative to absolute paths (PR #93281)

[via cfe-commits]

https://github.com/PeterChou1 created https://github.com/llvm/llvm-project/pull/93281

issue: https://github.com/llvm/llvm-project/issues/92867

I solved the problem by making the js use absolute path instead relative I think this also makes it more permanent since there is no need to compute relative path anymore
