Kubernetes version update script broken

[jacobtomlinson]

For the last few days the Kubernetes update script has been failing.

https://github.com/kr8s-org/kr8s/actions/runs/11676720158

Traceback (most recent call last):

Looks like endoflife.date has inconsistent data for the Azure Kubernetes Service which is causing the auto update script to break.

For Kubernetes 1.27 they appear to use the eol field for the LTS EOL date, and the lts and support fields for the original EOL date.

{
   "cycle":"1.27",
   "releaseDate":"2023-08-16",
   "eol":"2025-07-31",
   "lts":"2024-07-31",
   "link":"https://learn.microsoft.com/en-us/azure/aks/supported-kubernetes-versions?tabs=azure-cli#aks-kubernetes-release-calendar",
   "support":"2024-07-31"
}

but for 1.30 they seem to use the lts date for the original EOL date and the eol field for the LTS EOL date.

{
   "cycle":"1.30",
   "releaseDate":"2024-08-05",
   "eol":"2025-07-31",
   "lts":"2026-07-31",
   "link":"https://learn.microsoft.com/en-us/azure/aks/supported-kubernetes-versions?tabs=azure-cli#aks-kubernetes-release-calendar"
}

I've opened endoflife-date/endoflife.date#6166 to try and resolve the inconsistency upstream.
