Documentation: Kubernetes and Agones supported version matrix
Is your feature request related to a problem? Please describe.
Matching which version of Agones to a supported version of Kubernetes can be tricky to determine. You can access this via the dropdown, and go back to the snapshotted page, but it's hard to see all in one place.
Describe the solution you'd like
A table that lists each Agones version with each supported Kubernetes version, would make working this out much easier.
Something akin to: https://cloud.google.com/game-servers/docs/versions-and-upgrades#agones_and_kubernetes_supported_versions
Describe alternatives you've considered
Leaving things that they are, but that seems like it makes things more difficult for end users.
Additional context

Worth noting, from #2279 - the most accurate way to determine which version aligns with which Kubernetes version is the release notes.
