docs: remove unmaintained entries and add modern alternatives

- Web APIs: add django-ninja and apiflask, remove django-tastypie, flask-restful, and sandman2
- Web Scraping: remove grab and newspaper (unmaintained)
- Data Validation: remove colander and schematics (low activity)
- Testing: remove nose2 (superseded by pytest)
- Profiler: replace vprof with scalene (actively maintained, more capable)
- Package Management: remove mamba (redundant with conda)
