Update Source IP Tutorial: Replace Deprecated echoserver:1.4 with echoserver:1.10 for Compatibility

[colossus06]

Description

This PR updates the Docker image used in the Source IP for Services tutorial to registry.k8s.io/echoserver:1.10, replacing the deprecated version 1.4. The existing image (echoserver:1.4) is no longer supported due to its use of Docker Image Format v1 and Docker Image manifest version 2, schema 1, which have been deprecated in Kubernetes.

By updating to echoserver:1.10, this PR resolves image pull errors.

Warning  Failed     5m19s (x4 over 6m59s)  kubelet            Failed to pull image "registry.k8s.io/echoserver:1.4": [DEPRECATION NOTICE] Docker Image Format v1 and Docker Image manifest version 2, schema 1 support is disabled by default and will be removed in an upcoming release.

Changes made

Updated the image in the deployment command from registry.k8s.io/echoserver:1.4 to registry.k8s.io/echoserver:1.10.

Impact

• Resolves the ErrImagePull issue in the tutorial caused by the deprecation of the older image format.
• Ensures compatibility with current Kubernetes releases.

Localization Note

The deprecated echoserver:1.4 image is also referenced in some localized documentation, such as the Russian, Japan and Korean versions. It is recommended that these versions be updated as well to echoserver:1.10 for consistency across all languages.
