docs: Update repository name from wikijs-sdk-python to py-wikijs

Updated all repository URL references to reflect the new repository name:
- setup.py: Updated project URLs
- pyproject.toml: Updated project URLs
- README.md: Updated badges and installation commands
- CLAUDE.md: Updated deployment strategy
- docs/wikijs_sdk_release_plan.md: Updated repository URL
- docs/CONTRIBUTING.md: Updated clone URLs and issue tracker links

Note: Python package name remains 'wikijs-python-sdk' for consistency
with pip naming conventions. Only repository name changed.
