Document new configuration elements for Deployment resources

[mgencur]

What is changing?

There are a few configuration elements which are not documented yet in this document:

        QueueSidecarTokenAudiences sets.Set[string]

	// QueueSidecarRootCA is a root certificate to be trusted by the queue proxy sidecar  qpoptions.
	QueueSidecarRootCA string

	// DefaultAffinityType is a string that controls what affinity rules will be automatically
	// applied to the PodSpec of all Knative services.
	DefaultAffinityType AffinityType

	// RuntimeClassNames specifies which runtime the Pod will use
	RuntimeClassNames map[string]RuntimeClassNameLabelSelector

As defined in the config in this section

How will this impact our users?

In what release will this take happen (to the best of your knowledge)?

release-1.14
release-1.15

cc @ReToCode QueueSidecar* are documented in internal encryption?

That has nothing to do with internal encryption. I assume qpoptions is from https://github.com/knative-extensions/security-guard? @davidhadas
