Update k8s release cycle

[stonepreston]

Done

• Adds k8s 1.25 release information to chart
• Updates chart data to accurately reflect the N-2 and N-4 support windows. Previously the stair step pattern gives the impression that releases go out of support before they truly do. Now the N-2 and N-4 end dates are shown to be the end of the current release.

Moving to draft until we work out details regarding ESM support.

Thanks for taking this on @stonepreston and @kwmonroe! Could you update the copy doc to reflect these changes as well? Usually changes are made there first and then requested for the page. Tagging @evilnick as well in case you'd like to take a look.

Hi @stonepreston , is this ready for review?

[evilnick]

hi @mtruj013, thanks for looking at this. I think there are some issues we need to clarify about exactly what the different support terms mean, so we will likely need to update the language further in the next few days

No worries @evilnick! I'll move this out of the review/qa pipeline for now then 🙂
