Migrate cache.yml to use composite actions

- Replace conda-incubator/setup-miniconda with quantecon/actions/setup-lecture-env
- Replace manual LaTeX installation with quantecon/actions/setup-latex
- Replace manual jb build with quantecon/actions/build-lectures
- Benefits: Automatic caching, cleaner workflow, reusable patterns
