[BUG] ConfigConstraint Conversion Generates Incorrect Content After Upgrading KubeBlocks

[dingshun-cmss]

Describe the Bug

After upgrading KubeBlocks in a test environment:

1. The ConfigConstraint objects are upgraded by the upgrade hook from v1alpha1 to v1beta1, but the converted content is incorrect.
2. This results in the config-manager container disappearing after the DB cluster Pod is regenerated.

To Reproduce

1. Record the ConfigConstraint before the upgrade.
2. Create a test cluster before the upgrade.
3. Upgrade KubeBlocks following the steps outlined in the official documentation.
4. Record the ConfigConstraint after the upgrade. I found that all the properties in spec are missing, except for spec.immutableParameters and spec.staticParameters, which are retained.
5. Check the containers for the DB Pods.
6. Fix the ConfigConstraints and restart the test cluster; the config-manager container reappears.

Expected Behavior

The ConfigConstraint conversion from the upgrade hook should generate the correct content.

Additional Context

Upgrade from v0.8.4 to v0.9.1
