Description of problem:

The TestTLSDefaults test in openshift/origin was skipping when the cluster TLS profile was set to Modern (TLS 1.3), preventing proper test coverage in CI jobs configured with TLS 1.3 clusters (e.g., openshift-kubernetes-2315-ci-4.18-e2e-aws-ovn-tls-13).

The test would skip with the following message:

[sig-api-machinery][Feature:APIServer] TestTLSDefaults [Suite:openshift/conformance/parallel]
Reason: skip [github.com/openshift/origin/test/extended/apiserver/tls.go:126]: 
Cluster TLS profile is not default (intermediate), skipping cipher defaults check

Version-Release number of selected component (if applicable):

OpenShift 4.18 and later
Affected file: test/extended/apiserver/tls.go

How reproducible:

100% reproducible on clusters with Modern TLS profile (TLS 1.3)

Steps to Reproduce:

1. Deploy an OpenShift cluster with Modern TLS profile (TLS 1.3 only)
2. Run the TestTLSDefaults test from openshift/origin
3. Observe the test being skipped

Actual results:

The test skips execution on Modern TLS profile clusters, missing test coverage for TLS 1.3 behavior validation.

Expected results:

The test should execute on both Intermediate (TLS 1.2+) and Modern (TLS 1.3) TLS profile clusters:

• For Intermediate profile: test TLS 1.2+ connections and cipher suites
• For Modern profile: test that only TLS 1.3 connections succeed and TLS 1.0/1.1/1.2 connections fail

Additional info:

Fix implemented in PR https://github.com/openshift/origin/pull/30746:

• Replaced skip condition with a switch statement handling both Intermediate and Modern profiles
• For Intermediate profile: tests TLS 1.2+ and cipher suites (existing behavior preserved)
• For Modern profile: tests TLS 1.3 only (cipher suites skipped as they're not configurable in TLS 1.3)
• Uses dynamic minTLSVersion variable based on the detected profile
