Thumbnail gallery is not rendering properly

[symeneses]

Issue description

Building the dosc with the current versions (sphinx-gallery-0.11.0, sphinx-5.1.1) is breaking the thumbnail gallery: https://pymcio--404.org.readthedocs.build/projects/examples/en/404/gallery.html.

This build seems to be the last working build.

Last working versions:

• sphinx==5.0.2
• sphinx-gallery==0.10.1

In the release notes for 0.11 of sphinx-gallery, a similar issue was fixed in that version with this PR.

Before this, there was an issue building the docs that was fixed by pinning ablog<0.10.27 see https://github.com/sunpy/ablog/issues/151. See #404.

Yes, I will see if there is an error that we have or an issue in the updates. For now, the versions where the gallery is being displayed correctly were pinned in #404.
