Add one-click Launch Stack buttons to README

All 4 variants (Slurm GPU, Slurm Trainium, EKS GPU, EKS Trainium)
have working Launch Stack buttons that open CloudFormation console
with template URL, stack name, and lifecycle script params pre-filled.

Templates hosted at s3://hyperpodstackfiles/hyperpod-quickstart/.
Run scripts/publish.sh to regenerate buttons for a different bucket.
