oauth test failures related to CertificationVerificationError (go1.20)

Most recent nightly https://amd64.ocp.releases.ci.openshift.org/releasestream/4.14.0-0.nightly/release/4.14.0-0.nightly-2023-04-18-152947 has a lot of OAuth test failures

Example runs:

https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/periodic-ci-openshift-release-master-ci-4.14-e2e-aws-ovn/1648348911074545664

Error looks like:

fail [github.com/openshift/origin/test/extended/oauth/expiration.go:105]: Unexpected error:
    <*tls.CertificateVerificationError | 0xc0023b6330>: {
        UnverifiedCertificates: [
            {...


Looking at changes in the last day or so, nothing sticks out to me.

Although I believed ART bumped everything to be built with go1.20 and this error is new to go1.20:

"For a handshake failure due to a certificate verification failure, the TLS client and server now return an error of the new type CertificateVerificationError, which includes the presented certificates." - https://go.dev/doc/go1.20

4.14.0-0.nightly-2023-04-18-152947

Looks repeatable

1. Build oauth, origin, and related containers with go1.20 (not clear which is causing the test failure)
2.
3.

Tests fail
