Console reports wrong branch deployment time

### Environment information

```plain text
In the amplify console
```

### Describe the bug

Hello Team,

I noticed a behavior in the 'Overview' page regarding the branches' 'Last Deployment' section. The time displayed appears to be from the branch update rather than the actual deployment change.

Upon further investigation, I found that the last deployment time matches the 'updateTime' from the UpdateBranch API response.

Could you please clarify whether the Last Deployment section should reflect changes in the branch updates, or if this is a UI issue? Your assistance would be greatly appreciated.

I'm attaching an image for reference.

### Reproduction steps

N/A

Start at the Amplify console Overview page and compare the Last Deployment value with the updateTime returned by the UpdateBranch API. Confirm which timestamp the section should represent, then verify that the displayed value matches the actual deployment change rather than a branch update.
