Bump k8s-openapi for Kubernetes v1_32 support and MSRV (#1671)

* Bump k8s-openapi for Kubernetes v1_32 support

Signed-off-by: clux <[email protected]>

* Make just bump-k8s more reliable and parametrise k3s versions in CI

Technically expands our testing range a little bit, but it simplifies our gunk here.

Signed-off-by: clux <[email protected]>

* ci debug

Signed-off-by: clux <[email protected]>

* unparametrise, github does not support it

..nor does it support yaml anchors so back to hacks.

Signed-off-by: clux <[email protected]>

* Use a better replace due to gh not supporting env in params

Signed-off-by: clux <[email protected]>

* leftover env

Signed-off-by: clux <[email protected]>

* leftover env addition

* Bump MSRV to fix CI

brought in by home dep, but it's within our policy.

Signed-off-by: clux <[email protected]>

* should be consistent and use earliest in cargo.tomls

Signed-off-by: clux <[email protected]>

* remove ci check for specific e2e/cargo.toml openapi feature

given change to floating 'earliest' tag.
