`withlock` fails if `python` is missing

Hi SUSErs I just installed Leap 15.3, replacing 15.2, and noticed that the `withlock` package which requires `python39` fails because it expects python(2). I figured out that installing the `python` package will quickly fix this. Mfg Johann Log: ``` 43f06346a2a:/ # zypper in withlock ... The following 8 NEW packages are going to be installed: libexpat1 libpython3_6m1_0 libpython3_9-1_0 python-rpm-macros python3-base python39 python39-base withlock ... d43f06346a2a:/ # withlock /usr/bin/env: 'python': No such file or directory ```
