Remove papersaurus plugin - fix arm64 compatibility issue

[Copilot]

The papersaurus plugin was causing compatibility issues on arm64 systems due to its dependency on puppeteer, which was failing to install. This PR removes the papersaurus plugin entirely to resolve the installation and build issues.

Changes made

• Removed docusaurus-plugin-papersaurus dependency from package.json
• Removed papersaurus plugin configuration from docusaurus.config.js
• Updated package-lock.json to reflect the new dependency tree (removing ~6,300 lines of papersaurus-related dependencies)

Testing

The documentation site now builds and serves correctly:

• npm install completes without the previous puppeteer/arm64 errors
• npm run build generates the optimized production build successfully
• npm run serve starts the documentation server properly
• Build performance has improved significantly due to removing the heavy papersaurus dependency

All existing Docusaurus functionality is preserved. The author mentioned finding "a better way to make those PDFs" so this removal enables that alternative approach.

Fixes #530.
