ci: Test Python, Ruby crates

[langston-barrett]

These are currently disabled in the Makefile:

treeedb/Makefile

Lines 42 to 49 in 6bfcb3d

	.PHONY: test
	test:
	$(CARGO) build --locked $(CARGO_FLAGS) --workspace \
	--exclude treeedbgen-souffle-python \
	--exclude treeedbgen-souffle-ruby
	$(CARGO) test --locked $(CARGO_FLAGS) --workspace \
	--exclude treeedbgen-souffle-python \
	--exclude treeedbgen-souffle-ruby

We should figure out a way to test these in CI.
