Since serverless 1.7.0, mTLS for OpenShift Serverless moves to GA. We need to drop the IMPORTANT note in Integrating Service Mesh with OpenShift Serverless natively

TO BE REMOVED:

mTLS for OpenShift Serverless is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see https://access.redhat.com/support/offerings/techpreview/.
