What this PR does / why we need it:
Adds a dedicated Copilot skills file (doc/skills/acl-troubleshooting.md) for Azure Container Linux (ACL) troubleshooting, and a pointer to it from .github/copilot-instructions.md.
This enables AKS Node SIG engineers to use GitHub Copilot for diagnosing ACL-specific issues. The skills file covers:
ACL architecture (immutable host, UKI, sysexts, Ignition provisioning)
ACL-specific error codes (231, 232) and related ORAS errors
Component delivery via sysexts (kubelet, kubectl, GPU drivers) with registry paths
Log locations (CSE, Ignition, coreos-cloudinit, kubelet)
Troubleshooting workflows (debug pods, sysext failures, GPU issues, SELinux, package version identification)
Development guidelines for making ACL-safe changes in AgentBaker
Content is derived from the ACL TSG and AgentBaker source code.
