inject: add debug image annotations to ProxyAnnotations list

[mail2sudheerobbu-oss]

DebugImageAnnotation, DebugImageVersionAnnotation, and DebugImagePullPolicyAnnotation were missing from ProxyAnnotations. This caused namespace-level debug image annotations to not be inherited by pods (AppendNamespaceAnnotations only propagates annotations in the ProxyAnnotations list).

Fixes #13636

Hi @linkerd/maintainers 👋 — first-time contributor here, happy to be working on Linkerd!

This is a small focused fix for #13636: DebugImageAnnotation, DebugImageVersionAnnotation, and DebugImagePullPolicyAnnotation were absent from the ProxyAnnotations list in pkg/inject/inject.go. Since AppendNamespaceAnnotations only propagates annotations that appear in that list, namespace-level debug image settings were silently dropped and never inherited by pods.

The fix is a 3-line addition to ProxyAnnotations. No logic changes, no new dependencies. DCO passes and the branch merges cleanly with main.

Happy to add a test or make any other changes if needed. Thanks for your time! 🙏

This is not correctly formatted, needs more indentation.

Fixed! The three DebugImage annotation entries in pkg/inject/inject.go lines 84–86 were indented with a single tab instead of the double-tab used by all other entries in the ProxyAnnotations slice. Pushed commit 70d4156 to correct the indentation. Thanks for the catch!
