Package Alias: Multiple versions of npm package

Fahim’s text explains how to manage package versions when creating modules or plugins. Users can create custom aliases using npm to install specific package versions, such as “astro-v1” or “astro@1”. This allows for compatibility across different versions of the packages being used.
