Broken images on online version of the manual

See e.g. https://gap-packages.github.io/SimplicialSurfaces/doc/chap1_mj.html

I suspect this is because building your manual requires extra steps to create the images, and these steps are not run by CI?

Ah wait, of course that's not quite right: the online manual is only updated when you make a release. So if you use ReleaseTools then perhaps calling doc/tikz-files/recompile-images.sh from a .release script file would do it.

Or switching to that release GH workflow we've still not managed to complete sigh
