No network by default with Ubuntu 14 image from UTM gallery

**Describe the issue**
Hi, I installed the default Ubuntu 14 VM from the UTM gallery. My problem is that I don't have any network working with the default config.

**What I've tried**
I tried changing the network settings on the VM (From VLAN emulated to Advanced Bridge and Shared Networks) and at some point it was working but I needed to switch between Bridge and Shared networks at every VM reboot.

Today I had no network at all, even when I switched the networks settings. I think that I mess up with the VM so I tried to reinstall from scratch from the UTM gallery but now I have no network even if I change the network settings. I have tried modifying my VM linux network settings (tweaking the /etc/network/interfaces file etc) but without result.

The documentation does not help because it is for Ubuntu 22 so it does not apply to Ubuntu 14 as configuration file changed : https://docs.getutm.app/guides/ubuntu/#networking-is-unavailable

**Configuration**
* UTM Version: Version 4.3.5 (87)
* macOS Version: 14.3.1 (23D60)
* Mac Chip (Intel, M1, ...): M1

**Crash log**
No crash log.

**Debug log**
No debug log.
