Scrape commit email addresses for CNCF/K8s-Conformance for Conformance submissions for release 1.23-1.25

[Riaan Kleinhans]

We need the email addressses for sending out an Conformance change alert as discussed in Slack

[Caleb Woodbine]

There appears to be 153 commiters on v1.2{3,4,5} releases. 60 of which have noreply.github.com email address, to ignore or note.

git clone https://github.com/cncf/k8s-conformance
cd k8s-conformance
git log --format='%an <%ae>' -- v1.2{3,4,5}/* | sort -u

# without github emails
git log --format='%an <%ae>' -- v1.2{3,4,5}/* | sort -u | grep -v noreply.github.com
