Update test/sanity/ignore.txt from output.

README.md

Run bin/ansible-test sanity --test validate-modules --docker-no-pull --docker.

Put output into ignore-output.txt, and reduce to all ERROR: lines for validate-modules which inform about errors to be added or removed/ignored.

Run this script to update test/sanity/ignore.txt accordingly.
