[Bug] Root Authentication with fingerprint sensor doesn't work nicely

**Describe the bug**
My notebook has a fingerprint sensor, so I activated it. Unfortunately, it doesn't seem to work with the authentication used by distrobox. It silently asks for my fingerprint and then shows the password mask after about 30 seconds (fingerprint timeout), but I can't authenticate with my fingerprint.

**To Reproduce**
1. Buy a notebook with fingerprint sensor that is supported on Linux
2. Enroll fingerprints
3. (optional) configure PAM to use fingerprint for authentication
4. Create rootful distrobox
5. Export application from rootful distrobox
6. Try to start it using the .desktop entry

**Expected behavior**
I get asked directly for the password or (better) for my fingerprint.

**Desktop (please complete the following information):**
- Are you using podman, docker or lilipod? podman
- Which version or podman, docker or lilipod? podman version 5.5.1
- Which version of distrobox? distrobox: 1.8.1.2
- Which host distribution? Aeon Desktop
- How did you install distrobox? was preinstalled (so zypper)

**Additional context**
The issue might be solved by reyling on polkit instead of using sudo for authentication, but honestly, I have no idea how root is implemented in distrobox, so this really just is a first thought :)

If any additional information is required, please let me know :)
