Complete site generators documentation with all missing tools

Added missing site generators from README.md:
- Framework-specific: VuePress, Gatsby Docs Kit, MDX-GO, Fumadocs, Vocs
- Lightweight: Hugo was completely missing
- Enterprise: Document Node, Docsite, Portray, RcPress, xyd
- Experimental: Dokz, Gridsome

Enhanced extensions sections:
- Added Hugo Extensions
- Expanded Sphinx Extensions with consoletest, Contentui, Sphinx Substitution Extensions
- Added complete Sphinx Themes collection

Organization improvements:
- Better categorization by use case and target audience
- Added Hugo which was a major missing piece
- All generators from README.md now properly documented
- Maintained consistent structure with descriptions and best-use cases

This resolves the missing site generators issue.
