Refactor Makefile (#2457)

* handle artifact downloads; patch libs on install for kafka < 1
* export env vars
* no progressbar for wget
* Add lint: target; call pytest directly in test: recipe
* Use make targets in gh workflow; use java 21; drop java helper script
* add zstandard to requirements-dev
