[Bug 2049014] [NEW] software-properties-common is missing dependecy python3-six in Noble

[Edu Gómez Escandell]

Public bug reported:

Ubuntu version: "24.04 (Noble Numbat)"
software-properties-common version: 0.99.40

This command fails to run when package python3-six is not installed:

```
$ add-apt-repository -y --ppa ppa:ubuntu-wsl-dev/ppa
Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 14, in <module>
    from softwareproperties.shortcuts import shortcut_handler
  File "/usr/lib/python3/dist-packages/softwareproperties/shortcuts.py", line 23, in <module>
    from softwareproperties.ppa import PPAShortcutHandler
  File "/usr/lib/python3/dist-packages/softwareproperties/ppa.py", line 25, in <module>
    from launchpadlib.launchpad import Launchpad
  File "/usr/lib/python3/dist-packages/launchpadlib/launchpad.py", line 48, in <module>
    from launchpadlib.credentials import (
  File "/usr/lib/python3/dist-packages/launchpadlib/credentials.py", line 59, in <module>
    from six.moves.urllib.parse import parse_qs
ModuleNotFoundError: No module named 'six'
```

I reproduced this bug in docker. The following dockerfile exercises it:
```
FROM ubuntu:devel
ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update
RUN apt-get install -y software-properties-common
RUN add-apt-repository -y --ppa ppa:ubuntu-wsl-dev/ppa
```

Modifying the docker file by adding `RUN apt-get install -y python3-six`
before the last line works as a workaround.
