Describe the bug

Self hosted - Version 2.196.0

Feature segment override value provided by the webhook payload is incorrect (Enabled works as expected).
For example, I changed the segment override value from 48 to 49, clicked "Update Segment Overrides" and got back incorrect payload where prev values is 48 and new value is 48.

Steps To Reproduce

1. Set an environment Webhook.
2. Create a feature with one segment override
3. Set segment override value to 0.
4. Change the value from 0 to 1 and observe the JSON sent to the webhook.
5. Clone the segment override view and open it again.
6. Change the value from 1 to 2 and observe the JSON sent to the webhook.

Expected behavior

Expected to get the correct previous segment override value and the new segment override value.
