Expose the contracted JSON field name.

When a manifest or client uses spec.evictionConfig.memorySuppressionEvictionConfig, the field does not bind because EvictionConfig declares the JSON tag as beMemorySuppressionEvictionConfig. The generated CRD exposes only the be... property, so the intended key cannot configure this feature.

简体中文：当 manifest 或客户端使用 spec.evictionConfig.memorySuppressionEvictionConfig 时，该字段不会绑定，因为 EvictionConfig 声明的 JSON tag 是 beMemorySuppressionEvictionConfig。生成的 CRD 只暴露了 be... 属性，因此预期的 key 无法配置此功能。

Suggested fix 
-	BEMemorySuppressionEvictionConfig *BEMemorySuppressionEvictionConfig `json:"beMemorySuppressionEvictionConfig,omitempty"`
+	BEMemorySuppressionEvictionConfig *BEMemorySuppressionEvictionConfig `json:"memorySuppressionEvictionConfig,omitempty"`

Regenerate the AQC CRD after this change.

Review comment at @pkg/apis/config/v1alpha1/adminqos.go around lines 563 - 565:
Update the JSON tag on EvictionConfig.BEMemorySuppressionEvictionConfig to
expose the contracted memorySuppressionEvictionConfig property instead of the
be-prefixed name, and regenerate the AQC CRD so manifests using the contracted
key bind correctly.
