bug: asdf list all python blank output

[dideler]

Describe the Bug

Cannot list Python versions for installation via its plugin. This is specific to the python plugin as the asdf list all command still works as expected with other plugins.

Steps to Reproduce

1. Have asdf binary installed from GitHub Releases
2. Have python plugin installed
3. Have python version 3.13.2 installed
4. Run asdf list all python

Expected Behaviour

Shows a list of all available Python versions for installation

Actual Behaviour

Shows a blank output:

↪ asdf list all python

To add: asdf plugin add does not say anything about what happened.

➜   git:(master) ✗ asdf plugin add golang
➜   git:(master) ✗ asdf plugin add elixir
➜   git:(master) ✗ asdf install   

if plugin not installed then not error message

➜  git:(master) ✗ asdf install         
➜  git:(master) ✗ which asdf

To add, it assumes that the python installation is successful even if it failed. I'm using asdf version v0.16.5.

I got this message, even when the installation failed because of the lack of a C compiler.

asdf install python 3.12.4
version 3.12.4 of python is already installed

I was encountering the same situation.

In my environment, ~/.asdf/plugins/python/pyenv was empty.
Once I deleted the pyenv directory (which is also in .gitignore),
the pyenv directory was rebuilt on subsequent command executions, which seemed to fix it.
