What version of Org are you using?

I tried with both the latest release (9.3.7) and the current master
branch (220f2b0d9), using default configuration aside from

    (org-babel-do-load-languages
     'org-babel-load-languages
     '((shell . t)))

I see "/usr/bin/zsh" in both cases.

I tried using emacs -Q and org 9.4, and you're right, this bug is
nonexistent there. I am using Doom, so that's where the bug is coming from
most probably. Unfortunately, things don't work without that bug either.
The evaluation hangs indefinitely. I have used C-g to cancel them and take
a look at the session buffer:

I was able to reproduce it (with ksh, rather than zsh) on Org mode version 9.3.7 (release_9.3.7-705-gea9463 @ /home/nick/elisp/org-mode/lisp/).

#+BEGIN_SRC ksh :session z1
echo $HOME $0 $(which $0)
#+END_SRC

#+RESULTS:

#+BEGIN_SRC ksh
echo $HOME $0 $(which $0)
#+END_SRC

#+RESULTS:
: /home/nick ksh /usr/bin/ksh

Hmm.  If you step through org-babel-execute:shell, is shell-file-name
bound to the expected value of "ksh" (which should be let-bound outside
by org-babel-execute:ksh)?
