What this PR does / why we need it:

See #128849 (comment)

Test 1: DynamicProvisioner

ginkgo.DeferCleanup(updateDefaultStorageClass, c, scName, "true")
updateDefaultStorageClass(ctx, c, scName, "false")

Test 2: Retroactive StorageClass Assignment

ginkgo.DeferCleanup(func(cleanupContext context.Context) {
	// Restore existing default StorageClasses at the end of the test
	for _, sc := range defaultSCs {
		setStorageClassDefault(cleanupContext, client, sc.Name, "true")
	}
})

// Unset all default StorageClasses
for _, sc := range defaultSCs {
	klog.InfoS("Unsetting default StorageClass", "StorageClass", sc.Name)
	setStorageClassDefault(ctx, client, sc.Name, "false")
}

The updateDefaultStorageClass function sets storageclass.beta.kubernetes.io/is-default-class and storageclass.kubernetes.io/is-default-class annotations on the StorageClass. but the setStorageClassDefault function only sets storageclass.kubernetes.io/is-default-class annotation. Even though storageclass.beta.kubernetes.io/is-default-class is deprecated, it is still working in the cluster. so there is a flaky test failure in the Retroactive StorageClass Assignment test when it is excuted after DynamicProvisioner test.

In order to fix this issue, we need to replace the setStorageClassDefault function with updateDefaultStorageClass function in the Retroactive StorageClass Assignment test.

Which issue(s) this PR fixes:

Fixes #128849
