[clang-doc] The nightly llvm 16 debian packages are missing files

[danakj]

The package is clang-tools-16.

The following files are missing:

• index.js
• clang-doc-default-stylesheet.css

Running clang-doc-16 produces this error at the end:

error creating file clang-doc-default-stylesheet.css: No such file or directory

Emiting docs in html format.

Error: Process completed with exit code 1.

If you copy the style sheet in place, you get the same error for index.js:

error creating file index.js: No such file or directory

On an install from source, the files are at $install_dir/share/clang/

It looks like this may be a problem for older debian packages too, the file is not in https://packages.ubuntu.com/kinetic/amd64/clang-tools-15/filelist
