Holoscan 5.x Debian Installation

Release and platform checks

This skill targets Holoscan SDK 5.x. Select the requested 5.x release before choosing artifacts. Read its release notes and the matching SDK installation guide. Select the 5.x documentation version; an unversioned page may describe 4.x. For an unreleased checkout, use its docs/sdk_installation.mdx and DEVELOP.md. Early Access binary commands describe planned artifacts, so confirm publication for the exact release before installing. If unavailable, explain that status and offer holoscan-install-source; keep the requested 5.x version.
