[CI] Rename debug symbol names to avoid tripping up the auto-installer (#2441)

The auto-install logic (in the https://github.com/clangd/node-clangd repo)
downloads the first package that starts with `clangd-<platform>-`.

The previous naming of the debug symbols package would mean it matched
this pattern, and it could be downloaded by the auto-install process instead
of the actual binary package.

 Please attach the clangd stderr log if you can. (Usually available from the editor)
 If possible, run with `--log=verbose` - note that the logs will include the contents of open files!
 If this is a crash, try to put `llvm-symbolizer` on your PATH per the troubleshooting instructions.
