v1.33.0

⚠️ Note

We have determined an issue that prevents the Nvidia Device Plugin from starting on the aws-k8s-*-nvidia variants in this release. We have paused the rollout of the release. We recommend you do not consume Bottlerocket 1.33.0 if you use these variants.

Pre-release Note

This is the latest Bottlerocket release, and is currently being made available.
You may notice nodes upgrading to this new version, though it may not yet be available globally until the "pre-release" flag is removed.
