ci: Remove product brief generation from documentation workflow

Workflow Cleanup:
- Removed LaTeX-based product brief PDF generation step
- Removed Ghostscript dependency and PDF merging process
- Removed hardware image copying step for documentation
- Simplified dependencies installation (removed Ghostscript and documentation requirements)
- Removed product brief PDF from docs/ deployment
- Streamlined workflow to focus only on Sphinx documentation

This change simplifies the CI/CD pipeline by removing the product brief generation process and focusing exclusively on Sphinx-generated documentation (HTML + PDF).

Benefits:
- Faster build times
- Reduced dependencies
- Simpler workflow maintenance
- Focus on primary Sphinx documentation
