Broken links for upptime and example-notebooks

[asmacdo]

I'm not sure if this is from the subdomain move, but these links on the left-navigation bar don't work for me. I'm happy to fix, but I wasn't sure what the correct URLs should be.

https://dandiarchive.org/example-notebooks

Thank you. I have filed #170 and dandi/example-notebooks#109.
