Provide install manifests that do not contain the gateway-api admission server

[arkodg]

What would you like to be added:
A release artifact similar to https://github.com/kubernetes-sigs/gateway-api/releases/tag/v0.8.1 which contains the installation manifests for Gateway API CRDs and not the Gateway API admission server and related resources

Why this is needed:

Installing the Gateway API admission server is optional and all its functionality has been replaced by CEL validations

Is this kind of a part of #2319? We could merge them as it would seem reasonable for one body of work to take care of both at the same time.

@shaneutt yes its related to #2319, but imo having a smaller work item is much easier to track and assign to a community contributor

looks like https://github.com/kubernetes-sigs/gateway-api/blob/main/hack/build-install-yaml.sh needs to be updated to accomplish this goal, the question is around naming and content - should we just create a experimental-crds-install.yaml & standard-crds-install.yaml and keep the existing experimental-install.yaml & standard-install.yaml as is ?

I'm not sure we should start having all these extras laying around, I think we should just remove the admission server bits and be done with it, v0.8.0 (the last release intended to "support" the webhook) is branched and any future webhook development should probably be isolated to that branch.

cool @shaneutt, I can take care of this
