schemars 1 with kube pre-2 and k8s-openapi pins

[clux]

sanity test of pinned versions in kube for schemars 1 and rust 2024

only thing to test is whether metric timing still works:

warning: relative drop order changing in Rust 2024
    --> src/controller.rs:81:6
     |
63   | #[instrument(skip(ctx, doc), fields(trace_id))]
     |                                               - now the temporary value is dropped here, before the local variables in the block or statement
...
69   |     let _timer = ctx.metrics.reconcile.count_and_measure(&trace_id);
     |         ------
     |         |
     |         `_timer` calls a custom destructor
     |         `_timer` will be dropped later as of Edition 2024
