fix: Update docs workflow to generate Doxyfile from template

The Doxyfile is now auto-generated from Doxyfile.in template via CMake.
Updated the documentation deployment workflow to:
- Install cmake as a dependency
- Generate Doxyfile from template before running doxygen

This ensures the workflow works with the template-based version
management system.
