fix(ec2): show terminated icon on terminated instances. (#6092)

## Problem
The AWS SDK returns terminated instances for a short period and we
display a `pending` icon in this case.

## Solution
Display a specific icon that indicates the instance is terminated. 
<img width="606" alt="image"
src="https://github.com/user-attachments/assets/9bcaf466-6043-400e-bea2-394c3f7ec2fc">

## Alternative Solution 
We could have avoided showing terminated instances at all. However, by
showing them terminated it provides consistency with the console(since
it also shows terminated instances for a short period), and greater
visibility.
