ci: move cahce job to 3.13 for memory issue

Cache job is getting killed early, I think because we're running out of memory
because the sheer number of CVEs has gotten too large. Things seem to work
better on python 3.13 (likely due to other memory improvements) so this is an
attempt at a temporary workaround while we address the underlying issue.
