docs: Fix "No module named 'imghdr'" when building website

Between Mitogen 0.3.19 & 0.3.20 Netlify changed their default Python to 3.13. This broke our deployment of https://mitogen.networkgenomics.com/. The previous default was Python 3.8, based on a recent successful build of https://spiffy-croissant-696d93.netlify.app.
