Webfonts return 404

[dennis-tra]

Our website measurements showed a very low number of samples for the docs.libp2p.io website: https://github.com/protocol/network-measurements/blob/master/reports/2023/calendar-week-8/ipfs/README.md#website-monitoring

After looking into this, there are two problems:

• The tool we're using (phantomas) errors out if the first response has a >= 400 status code
• The webfonts return a 404
