Upgrade to Catlab 0.17

[Saityi]

This PR:

1. Disables some functionality (Rewriting, n_stratify), integrating Temporarily disable unused dependencies in StockFlow.jl and Rewrite.jl #141, which this supersedes
   • n_stratify is not used in any examples and appears to be primarily to make stratification easier to use. The other stratification DSL appears to still function
2. Updates remaining functionality to use Catlab 0.17; examples of this include src/syntax/Stratification.jl L334 (pullback usage) and tests (test/syntax/Stratification.jl, pullback usage and is_natural)
3. Removes old StockAndFlow data types no longer in use
4. Deletes older examples not using the DSL
5. Disables the Literate.jl (docs) step of CI
6. Updates the notebook validation step to match new examples

This currently passes the unit tests and the notebook examples validate. Notebook validation is expected to fail pending TODOs

TODOs:

1. Update all examples in examples/ to use Catlab 0.17 Addressed by @Yuge168
2. Figure out why some n_stratify examples work but others don't (compare chain_ltype, which fails with an exception, and age_weight_5 (which is successfully stratified). n_stratify has been commented out and will be revisited at some other point
