This commit bumps library-go to include the latest changes. It acts as a proof PR for openshift/library-go#2455 .

This fixes an issue seen when oc client is used to login to a HCP cluster on macOS. This allows oc to login successfully.

verifyServerCertChain() now has a check that returns an unknown authority error when it detects macOS and a string based x509 error.

It falls back to kubeconfig CA when a string based x509 error is observed on the macOS platform.

This fix resolves a major issue introduced in a recent change
where logging in using oc on macos to a hcp client with insecure
flag was used.

On other clusters where there was no error, the
check now panics on strings.HasPrefix(err.Error(), ...) as there
was no check to see if err != nil.

This was flagged by coderabbitai in library-go bump pr in oc.

openshift/oc#2391 (comment)

This change move darwin cert verify logic out of verifyServerCertChain,
and additionally, adds a unit test that actually tests the error logic
for darwin based systems.

Additionally, this commit simplifies the error checking process by wrapping the
error in a custom error for better readability. it also simplifies
the error checking and unit tests for this problem.

It demonstrates the change in action in oc.
