Summary

Description:

• Tool repo URL: https://github.com/chaaz/versio
• Plugin repo URL: https://github.com/pdemagny/asdf-versio

Checklist

• [x] Format with scripts/format.bash
• [x] Test locally with scripts/test_plugin.bash --file plugins/<your_new_plugin_name>
• [x] Your plugin CI tests are green
  • Tip: use the plugin_test action from asdf-actions in your plugin CI

(The CI on the plugin is not green for MacOS because of missing openssl lib on the runner, but the asdf plugin itself downloads the binary as it should).
