Lightweight version for Node.js backend

[dec0dOS]

When installing the @app-config/main@2 package, you might notice some warnings and a substantial number of dependencies being added:

❯ npm install @app-config/main@2
npm WARN deprecated json-schema-ref-parser@9.0.9: Please switch to @apidevtools/json-schema-ref-parser
npm WARN deprecated @types/bson@4.2.0: This is a stub types definition. BSON provides its own type definitions, so you do not need this installed.

While the app-config library is fantastic, it might seem excessive if you simply want to load and validate configuration files for your Node.js backend. The surplus dependencies can introduce supply chain risks and increases the container image, and the presence of high-severity vulnerabilities in deprecated packages can be concerning.

This issue is particularly relevant for Node.js backend servers, where you don't need the CLI or other unnecessary dependencies on your production server. Instead, these should be declared as devDependencies.

I'd like to inquire if there are any plans to introduce a more lightweight solution tailored for Node.js. This would greatly benefit users who want a simpler, streamlined approach to config loading and validation for their backend servers.
