Provide Kubernetes version compatibility matrix

[diversario]

Is your feature request related to a problem? Please describe.
I am preparing for a round of cluster upgrades and I'm trying to understand what Kubernetes versions (1.27+) Argo Events supports.

Describe the solution you'd like
A table like the one provided by Argo Workflows, clearly stating AE vs k8s version compatibility.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
This feature request is identical to argoproj/argo-workflows#8198 and argoproj/argo-cd#12276.

+1 for a k8s compatibility table. We have deferred upgrading our cluster for this reason, and are starting to incur costs due to the lack of upgrades, so I started digging to find an answer.

Please correct me if anything is incorrect:

Current supported version

As I understand, the current k8s.io/api version is 0.29.2, updated 8 months ago in #3107

Does this mean the latest currently supported Kubernetes version is 1.29.2 ?

no it doesn't mean that, an argoworkflows version that has api version of 0.24 (https://github.com/argoproj/argo-workflows/blob/v3.4.11/go.mod#L64) still runs fine on my 1.29 cluster. i'm sure 1.31 cluster will handle current argo-events just fine, upgrade your cluster!

In addition to k8s version compatibility, I think maybe we also need to include argo-workflow version in the matrix since argo-events should be coupled with argo-workflow.

It's can easily be verified through code, but I think it's can be added into both operation manual.
