Incorrect imports of `schemars` type

Current and expected behavior

Compile error on mismatched types.
The hard coded import in schema.rs file can change with feature flags.
This type changes with the preserve_order flag in schemars.

Possible solution

This line:

kube/kube-core/src/schema.rs

Line 5 in b92dc5b

use std::collections::btree_map::Entry;

Should be changed to:

use schemars::MapEntry as Entry;

or just use schemars::MapEntry; and change the match lower down in the code (line 104-114).
