[docs] Disable numpy intersphinx (#10752)

These links usually 403 for us which `task_python_docs.sh` is set up to ignore, however sometimes it hits a 404 error which has been causing CI failures lately (e.g. https://ci.tlcpack.ai/blue/organizations/jenkins/tvm/detail/main/2832/pipeline/). This disables intersphinx links to numpy entirely until we can sort out a better fix.
