feat: add support for premium slug in generateConfig function (#647)

* feat: add support for premium slug in generateConfig function

- Introduced a new condition to handle slugs that include "premium/", allowing for better categorization in the configuration generation process.

* refactor: update CloudPlan import paths across components

- Replaced imports of CloudPlan from "shared/useCloudPlan" to "shared/interface" for consistency and clarity.
- Adjusted related components to ensure proper usage of the updated CloudPlan type definition.

* feat: extend EXTENDS_FOLDERS to include premium plan

- Updated the EXTENDS_FOLDERS constant to include "premium" as a valid CloudPlan option, enhancing the flexibility of the table of contents generation.
- Adjusted the type definition to ensure consistency with the new CloudPlan import.

* feat: add CloudPlan type to path.ts for enhanced configuration

- Imported CloudPlan into path.ts to support additional configuration options.
- Updated the prefix variable type to CloudPlan | undefined for improved type safety in the generateConfig function.

* feat: restructure page creation logic by modularizing create-pages functionality

- Removed the existing create-pages.ts file and replaced it with modular files for creating specific pages: create-docs, create-doc-home, create-cloud-api, create-search, and create-404.
- Introduced an interface file to define common types and constants, enhancing code organization and maintainability.
- Each new file encapsulates the logic for creating its respective page, improving clarity and separation of concerns in the page generation process.

* refactor: simplify prefix determination in generateConfig function

- Replaced multiple conditional checks for slug prefixes with a more concise approach using an array and the find method.
- Maintained the existing logic for handling the dedicated prefix based on the presence of a name, improving code readability and maintainability.

* fix: update template import paths in page creation files

- Adjusted the import paths for template files in create-404, create-cloud-api, create-doc-home, create-docs, and create-search to ensure correct resolution.
- Enhanced consistency across page creation logic by standardizing the path structure.
