upgrade kubernetes patch versions 1.29.9, 1.28.14

We need to upgrade the kubernetes patch versions to:

• 1.29.9 (or later)
• 1.28.14 (or later)

Inspiration can be taken from what was done in !2268 (merged):

• upgrade of k8s_version_map
• upgrade of diskimage builder version
• any needed adjustment in calico and ingress-nginx chart versions
• updates of image_key
