contao-manager, core-bundle, installation-bundle, managed-edition, core

[math-GH]

There are different packages on Github and different terms for a Contao installation:

• Conta manager
• Core bundle
• installation bundle
• managed edition
• core

There should be a short overview an description about that different installation packages.
(f.e. on that overview site: https://docs.contao.org/books/manual/4.4/en/01-installation/)

On that page is just a short hint which packages to use:
https://docs.contao.org/books/manual/4.4/en/01-installation/installing-contao.html
("You can also install Contao with Composer using the contao/managed-edition repository.")

What does it mean to use the managed edition? why not core bundle?
