Images not rendered on website for data access tutorial

[scottyhq]

For example:

https://icesat-2-2023.hackweek.io/tutorials/data-access-and-format/earthdata_search.html#searching-for-data-and-s3-links-using-earthdata-search :

You can use this syntax to get images and captions appearing identically on the website and jupyterhub (https://jupyterbook.org/en/stable/content/figures.html#figures):

```{figure} ../images/C-3PO_droid.png
---
height: 150px
name: directive-fig
---
Here is my figure caption!
```

@andypbarrett @asteiker are one of you able to open a follow-up PR to fix? If you don't have time today we can get to it later, since as mentioned above things look good running the notebook in CryoCloud JupyterHub
