Remove problematic metadata

ageorgou · ageorgou · commit 162d6ff948db · 2022-10-04T15:08:51.000+01:00
This caused issues with newer nbconvert on some files. I don't
see any noticeable differences in the output, apart from figures
being a bit bigger. Changing it on all files where it appears,
for consistency.
