Documentation snippet about kubernetes detection is not working as expected

One way to resolve this is to add a feature to your library that enables one of the k8s-openapi v1_* features and is used only when running such commands.

The point of that line in the docs is that you define the __check feature as you did and then run cargo check --features __check. Just cargo check will continue to fail.

I'll change it to not use passive voice so that it's clear that it's not like it's a cargo behavior to use that feature automatically.

Thanks! I was hoping that cargo check would run by default with this feature by default 😅

@flavio You're likely seeing this because of the resolver change in rust 2021.

What we do to make this more ergonomic for libraries (that are ultimately not responsible for picking kubernetes versions) without breaking cargo check / cargo publish, is to add a dev-dep entry to k8s-openapi for local use:

[dev-dependencies.k8s-openapi]
version = "0.16.0"
default-features = false
features = ["v1_25"]

@clux this is not taken into account by commands like cargo check. This works only when doing cargo test.

The documentation of the project is already clear about this limitation.
