fix: Fargate provider storage size setting doesn't work (#661)

- Corrected the logical grouping of the nullish coalescing operator and ternary operator for the ephemeralStorageGiB property.
- Ensured that the ephemeralStorageGiB property is correctly set when provided in the props.
- This fix ensures that the correct storage value is reflected in the synthesized CloudFormation template.
- Prior to this fix the storage value would always be set to 25
