[Error] Distrobox fails to create nvidia container

**Describe the bug**

When trying to build distrobox, it fails with error

```

```

It seems to be trying to eval the banner of Nvidia containers.

**To Reproduce**

distrobox.ini
```
[cuda-dev]
image=docker.io/pytorch/pytorch:2.8.0-cuda12.6-cudnn9-devel
nvidia=true
init=true
additional_packages="systemd dbus dbus-user-session iproute2 procps"
```

command
```
distrobox-assemble create --file ./distrobox.ini
```

**Expected behavior**
Distrobox created without error

**Desktop (please complete the following information):**
versions:
distrobox: 1.8.2.0
Linux bazzite 6.17.7-ba13.fc43.x86_64 #1 SMP PREEMPT_DYNAMIC Fri Nov 14 20:03:53 UTC 2025 x86_64 GNU/Linux
podman version 5.6.2

/usr/bin/distrobox-create 的第 1072 行發生錯誤，其中 eval 命令因 NVIDIA 容器橫幅而遇到語法錯誤。首先檢查該行附近的 distrobox-create 指令碼，以了解它如何處理容器輸出。尋找當 nvidia=true 時，指令碼如何處理容器橫幅或初始輸出。使用一個簡單的容器進行測試，以確認問題是否特定於 pytorch 映像。修正可能涉及在 eval 之前篩選或跳脫橫幅文字。
