Doesn't work on Babashka

[edenworky]

The cider.nrepl.print-method namespace [makes use of clojure.core/print-object'](https://github.com/clojure-emacs/cider-nrepl/blob/master/src/cider/nrepl/print_method.clj#L30) (and maybe print-methodtoo?). Of these, [the ClojureDocs](https://clojuredocs.org/clojure.core) listprint_methodas undocumented and doesn't listprint_objectat all, and indeed [theclojure/core.cljfile](https://github.com/clojure/clojure/blob/master/src/clj/clojure/core.clj) definesprint_methodand usesprint_object` but doesn't define it.

In any case and for whatever reason, Babashka doesn't include a clojure.core/print-object function, and therefore trying to (require 'cider.nrepl) under a Babashka REPL throws a clojure.lang.ExceptionInfo: Unable to resolve var: clojure.core/print-object [at cider/nrepl/print_method.clj:37:1]. Since this happens on require, I can't figure out a way of configuring *pretty-objects* either, so for now I have no way of running cider on a Babashka nREPL server.
