rsvg-convert doc only mentions all lowercase format options, so looks 
fine to me

FYI, --format=pdf is a "moving" target, that is it isn't always the same 
PDF version depending on rsvg-convert's own version. They mention it can 
be an issue with some latexpdf versions only supporting older PDF 
versions. See 
https://github.com/GNOME/librsvg/blob/main/rsvg-convert.rst#pdf-versions

At least you're aware of it now, no idea if we should be doing something 
about it. I guess we could try to be smart and detect the max PDF 
version supported by latexmk at runtime and select the pdf version for 
rsvg-convert based on that.

Thanks!
Quentin
