[Error]: distrobox rm ignores `container_name_default` from `~/.distroboxrc`

**Describe the bug** When using `container_name_default` in `~/.distroboxrc`, the value is respected by `distrobox create` and `distrobox enter`, but not by `distrobox rm`, which uses an incorrect container name. **To Reproduce** 1. Configure `~/.distroboxrc` with: ```bash container_name_default="dev" ``` 2. Run: ```bash distrobox create ``` The container is created with the correct default name (`dev`). 3. Run: ```bash distrobox enter ``` The command enters the correct container (`dev`). 4. Run: ```bash distrobox rm ``` The prompt shows: ```text Do you really want to delete containers: my-distrobox? [Y/n]: ``` This uses the wrong container name instead of the configured default. **Expected behavior** `distrobox rm` should use the same `container_name_default` value defined in `~/.distroboxrc`, consistently with `distrobox create` and `distrobox enter`. **Logs** Not attached yet. **Desktop (please complete the following information):** - Are you using podman, docker or lilipod? - podman - Which version of podman, docker or lilipod? - podman 5.8.2 - Which version of distrobox? - 1.8.2.4 - Which host distribution? - Fedora Linux 44.20260507.0 (Kinoite) - How did you install distrobox? - `rpm-ostree install distrobox` **Additional context** This seems to affect only `distrobox rm`. Other commands such as `distrobox create` and `distrobox enter` correctly respect the value set in `~/.distroboxrc`.
