What it does

This class processes Magento 2 configuration by extracting values from environment variables.

Developers use this when they want to store sensitive configuration data (like API keys, database credentials) in environment variables instead of hardcoding them in config files.

It automatically replaces configuration placeholders with their corresponding environment variable values during the config loading process.
