[2.2.x] composer init command does not honor composer schema for authors

[llaville]

Begin with a fresh project, so I used the composer init command.

Output of composer diagnose:

When I run this command:

composer init

I get the following output:

And I expected this to happen: No prompt error when I enter only "John Doe", because :

• Author definition in composer schema : https://github.com/composer/composer/blob/main/res/composer-schema.json#L608-L637
• Only name is required: https://github.com/composer/composer/blob/main/res/composer-schema.json#L615
