Document the cflinuxfs5 stack (derived from Ubuntu 24.04 LTS "Noble Numbat") as an additional Linux stack available in Cloud Foundry. cflinuxfs4 remains the default; operators enable cflinuxfs5 by applying the add-cflinuxfs5.yml experimental ops file from cf-deployment. Update the example 'cf stacks' output to reflect both ACTIVE stacks. Signed-off-by: Ivo Radkov <ivo.radkov@sap.com>

Summary
Document the
cflinuxfs5stack (derived from Ubuntu 24.04 LTS "Noble Numbat") as an additional Linux stack available in Cloud Foundry.Changes
cflinuxfs4(default) andcflinuxfs5.cflinuxfs5is currently enabled via theadd-cflinuxfs5.ymlexperimental ops file incf-deployment, whilecflinuxfs4remains the default.cflinuxfs5stack receipt.cf stacksoutput to includecflinuxfs5asACTIVE.Why
Application developers currently have no way to learn from the official docs that
cflinuxfs5exists or how it can be enabled in their foundation. The stack rootfs (cloudfoundry/cflinuxfs5) and the BOSH release (cloudfoundry/cflinuxfs5-release) are published, and the experimental ops file incf-deploymentallows operators to opt in today.Notes
cflinuxfs5is described as opt-in via the experimental ops file. Oncecflinuxfs5is promoted directly intocf-deployment.yml(as planned), a follow-up PR should drop the "experimental" wording.windows-stacks.html.md.erb.
