feat(content-types): allow custom root paths for CT managers

[Convly]

Original idea by @alexandrebodin in #24 (comment)

Custom Path Support for Content Types Manager 🎯

Introduce a new feature that allows users to customize the path for the content-type managers' instance.

It aims to provide greater flexibility in how queries are made against Strapi app, especially those having heavy customization (or simply want to use the CT managers for plugins' models)

Custom Path Configuration

• Developers can now specify custom paths for content types managers from the client's calls
  • strapi.collection('foo', { path: '/plugin/baz/foo' });
  • strapi.single('bar', { path: '/my-custom-path' });

🧪 Testing

• Unit tests added for new path configuration functionality
• Manual testing performed across the different demos

📚 Documentation

Documentation has been updated to include:

• Configuration guide for custom paths
• Examples of common use cases
• Updated outdated demo list to include the react-vite one
