Bug Report

Q	A
Version(s)	3.3.0

Summary

When installing all my dependencies, I get Undefined array key 2 after selecting [2] config/config.php

Current behavior

Undefined array key 2

How to reproduce

Can reproduce this locally, but it happens when having a mezzio project with laminas-cache and laminas-cache-storage-adapter-redis.

  Please select which config file you wish to inject 'Laminas\Cache\Storage\Adapter\Redis\ConfigProvider' into:
  [0] Do not inject
  [1] config/development.config.php.dist
  [2] config/config.php
  Make your selection (default is 1):2

  Remember this option for other packages of the same type? (Y/n)

Expected behavior

No error occurs.

This most probably relates to #68
Nah, have the same issue with 3.2 and 3.1 and 3.0, so its not related...
