`ncu-ci walk pr` handling of very broken CI runs

Today's CI reliability GitHub actions run failed running ncu-ci walk pr --stats=true --markdown $PWD/results.md:
https://github.com/nodejs/reliability/actions/runs/1904541710

The log is too big to be displayed in the web UI but downloading the log shows that ncu-ci ran out of memory
