Remove usage of `Endpoints`

[dervoeti]

We use Endpoints here:

zookeeper-operator/rust/operator-binary/src/discovery.rs

Lines 201 to 212 in d8af61f

	let endpoints = client
	.get::<Endpoints>(
	svc.metadata.name.as_deref().context(NoNameSnafu)?,
	svc.metadata
	.namespace
	.as_deref()
	.context(NoNamespaceSnafu)?,
	)
	.await
	.with_context(|_| FindEndpointsSnafu {
	svc: ObjectRef::from_obj(svc),
	})?;

They are deprecated as of Kubernetes 1.33 (we should probably use EndpointSlices instead).

This should be moot once we listenerify.
