Fix GitHub Actions workflows

- Update CMake variable names (DNWGRAPH_BUILD_* instead of DNW_GRAPH_BUILD_*)
- Replace unavailable custom container with standard ubuntu-latest runner
- Use peaceiris/actions-gh-pages for deployment
- Only build docs on master branch push
- Update to actions/checkout@v4
