Move Feature GKEAutopilotExtendedDurationPods to Beta

[markmandel]

Prerequisites:

• Update Supported Kubernetes to 1.28, 1.29, 1.30 #3919

Once the above is completed, our lowest supported K8s version will be 1.28.x, so we should be able to bump this to beta.

@zmerlynn - any objections to the above?

[zmerlynn]

AutopilotPassthroughPort just went to Beta after the last release, @vicentefb did that in #3916

However, because you're referencing k8s version numbers, did you perhaps mean GKEAutopilotExtendedDurationPods?

I would still like GKEAutopilotExtendedDurationPods to go through Beta and not go straight to Stable, and we may want it to hang out in Beta for several releases as it changes the default scheduling policies on Autopilot for all Agones pods.

Blerg, I missed this one several levels 🤦🏻‍♂️

1. Yes I meant GKEAutopilotExtendedDurationPods
2. Yes, I meant moving to Beta.
3. I did just also realise that AutopilotPassthroughPort is listed as alpha at https://agones.dev/site/docs/guides/feature-stages/#feature-gates

So, updated ticket, and also any issue with moving to Beta.

[zmerlynn]

No objection now. :)

Well, it's ready to go after #3919, as mentioned above. :)
