Download through UTM doesn't resume if broken/interrupted

**Describe the issue**
Clicked the Download link on the UTM site to grab the Debian 11 LXDE image, to open directly in UTM. It progressed until about 30% then failed. If I try to restart, it starts again from 0%. I was expecting it to resume from the point upto which download had completed.

**Configuration**
* UTM Version: 4.6.3 (106)
* macOS Version: Sequoia 15.1
* Mac Chip (Intel, M1, ...): M4
