[website] general broken links

It might be a good idea to run a scheduled link checker like https://linkchecker.github.io/linkchecker/ - I'm not sure it's the best tool but it will do the trick.

Add more urls to --no-follow-url to ensure it will check all outbound links from https://www.deepspeed.ai/, like https://deepspeed.readthedocs.io, otherwise it skips checking outbound links.

$  linkchecker -r -1 https://www.deepspeed.ai/ --no-follow-url https://deepspeed.readthedocs.io
