Add sagemaker-ai plugin (re-list after YAML fix)

sagemaker-ai was dropped from the marketplace in #1762 (validate-plugins
adoption) due to a manifest/YAML error. AWS has since fixed it; the plugin
validates clean at awslabs/agent-plugins@187edde (claude plugin validate passes).

Re-listed as a git-subdir source SHA-pinned to current monorepo HEAD,
matching its sibling AWS entries (deploy-on-aws, databases-on-aws).
