This change updates kubernetes package from 1.29.1 to 1.29.2
and it uses golang-1.21.7.
Test Plan:
PASS: kubernetes-1.29.2 package builds successfully
PASS: All packages build successfully
PASS: Build ISO successful with multiple kubernetes versions
PASS: For pkg-versioning, add a dummy commit to subdirectory
of kubernetes-1.29.2. Built package kubernetes-1.29.2
and verified that package version was incremented by 1.
PASS: Install the ISO as AIO-SX and verify the K8s 1.29.2 staged
binaries are present in the path /usr/local/kubernetes/1.29.2
