Re-export deprecated type alias and improve deprecation guidance

[clux]

Follow-up to #1875 to make the breaking change less jarring for people using the type from this re-export. It also updates the deprecation warning to guide people to the new pattern.

---

Before (using the deprecated ErrorResponse from kube::error); fails and no deprecation;

error[E0422]: cannot find struct, variant or union type `ErrorResponse` in module `kube::error`
   --> src/controller/reconcile.rs:129:39
    |
129 |         kube::Error::Api(kube::error::ErrorResponse { code: 403, .. }) => {
    |                                       ^^^^^^^^^^^^^ not found in `kube::error`

For more information about this error, try `rustc --explain E0422`.
error: could not compile `xctrl` (lib) due to 1 previous error

---

After

warning: use of deprecated type alias `kube::kube_core::ErrorResponse`: use kube::core::Status instead.

         Note that the Error::Api constructor based pattern matches have been helper functions due to boxing.
           See Status docs for the new pattern:
           https://docs.rs/kube/latest/kube/core/struct.Status.html
   --> src/controller/reconcile.rs:129:39
    |
129 |         kube::Error::Api(kube::error::ErrorResponse { code: 403, .. }) => {
    |                                       ^^^^^^^^^^^^^
    |
    = note: `#[warn(deprecated)]` on by default

error[E0308]: mismatched types
   --> src/controller/reconcile.rs:129:26
    |
128 |     .map_err(|error| match error {
    |                            ----- this expression has type `kube::Error`
129 |         kube::Error::Api(kube::error::ErrorResponse { code: 403, .. }) => {
    |                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected `Box<Status>`, found `Status`
    |
    = note: expected struct `Box<kube::kube_core::Status>`
               found struct `kube::kube_core::Status`

so hopefully people look at the warning
