Looking at the open PRs, I do see one that is trying to add 1.33 to the EKS platform versions already but is over a month old. Let me know if you'd rather just include that and I can close this PR.

Edit: Looks like adding 1.33 has been merged into main, edited to just be removing the older unsupported versions of EKS

Thanks for the contribution! :)

It looks like 1.27 has been dropped for extended support now too, included that removal in the change set
