What this PR does / why we need it:

This PR adds directives to imagevector/images.yaml to leverage the new update-images script functionality introduced in gardener/cc-utils#1572.

The directives control how image entries are automatically updated:

• max-supported-k8s: Added to entries with >= 1.35 targetVersion to prevent creating entries for Kubernetes versions not yet supported by Gardener

Which issue(s) this PR fixes:
Fixes #

Special notes for your reviewer:

• CSI provisioner and resizer entries have explicit k8s version constraints (require k8s 1.34+). This means based on the changes in Enhance update-images.py with directives and comment preservation cc-utils#1572, they get updates to the highest available version. The fallback image without the k8s version constraint will only get patch updates.
• Once a new k8s version is supported in Gardener, the max-supported-k8s directive can be removed, and the update workflow triggered. After the new image versions for the new k8s version are added, the directive should be added to the latest version again.
• The max-supported-k8s directive on the ecr-credential-provider is not added since another auto-update should add the image just created for k8s version v1.35.1: https://github.com/gardener/ecr-credential-provider/releases/tag/v1.35.1

Release note:

[github-actions]

This change adds a comment marker to the Kubernetes images configuration file, likely for version management or documentation purposes. The modification appears to be a minor organizational update to help track maximum supported Kubernetes versions in the cloud provider AWS configuration.

Walkthrough

• Documentation: Added inline comment marker # max-supported-k8s to the images configuration file for better version tracking and documentation of Kubernetes compatibility limits
