[Flink K8s Operator] Trigger nonce missing for manual savepoint info

[Paul Lam]

Hi,

I’m using K8s operator 1.3.1 with Flink 1.15.2 on 2 K8s clusters. Weird enough, 
on one K8s cluster the flink deployments would show savepoint trigger nonce. 
while the flink deployments on the other cluster wouldn’t.

The normal output is as follows:

```
      Last Savepoint:
        Format Type:    CANONICAL
        Location:       
hdfs://.../savepoints/61dfcb2fd7946a0001827c55/savepoint-a81885-68d00e5130b8
        Time Stamp:     1689145852437
        Trigger Nonce:  2
        Trigger Type:   MANUAL
``
 And the erroneous output is like this (without trigger nonce and format type):
```
      Last Savepoint:
        Location:      
hdfs://.../savepoints/61dfcb2fd7946a0001827c55/savepoint-31c74e-3347299b84ec
        Time Stamp:    1689150184799
        Trigger Type:  MANUAL
``` 

Do you have any ideas about what’s causing this? Thanks!

Best,
Paul Lam
