Emit #[schemars(crate)] attribute

[Techassi]

Motivation

The JsonSchema derive macro will use an incorrect import of schemars which does not match the customized import via #[kube(crates(schemars = ...))]. In my case, this was undiscovered until now, because previously, schemars was available at the top-level through a dependency declaration in Cargo.toml.

Solution

This PR simply adds the #[schemars(crate = ...)] attribute to the generated CRD struct.

[Techassi]

Alright, I have noticed that we have to be a little cleverer and conditionally emit the attribute only when the schema mode is Derived.

Both CI failures seem unrelated to my change... Let me know if there is anything I need to fix.

Looks all very reasonable to me. Thank you!

[clux]

Integration test failure (clearly unrelated) seems to have become flaky somehow. The latter* test failure is my own fault for dropping openssl support in muslrust :/

Merging and fixing up CI after.

Thank you for the quick merge!
