fix(recipe): align AKS training K8s floors with DRA-GA >= 1.34 rationale

[mohityadav8]

Bumps the remaining AKS training leaves (aks-training, a100/h100 base, ubuntu, and kubeflow overlays) from >= 1.30 / >= 1.32.4 to >= 1.34, matching the DRA-GA rationale already stated in aks.yaml. The Slurm leaf was already correct (bumped in #1744).

Extends TestH100AKSUbuntuTrainingSlurmFloorNotClobbered with sibling leaf cases so the whole AKS training family's resolved floor is pinned, not just the Slurm leaf. Syncs the resolved example recipe.

Fixes: #1772

📝 Walkthrough

Walkthrough

AKS training recipe overlays for the general, A100, and H100 variants now require Kubernetes server version >= 1.34 instead of lower floors. The metadata store regression test was expanded to cover additional AKS training combinations and verify that the resolved floor remains >= 1.34.
