bug#52878: [PATCH] Fix display-comint-buffer-action default behavior

[Morgan . J . Smith]

From: Morgan Smith <Morgan.J.Smith@outlook.com>

* lisp/window.el (display-comint-buffer-action): Make it an alist.
---

This is my first real contribution to Emacs :)

My copyright papers are all good (not that it matters for this).

The recent change that added display-comint-buffer-action does not do what it 
was supposed to.  Since it is not a list, when it gets passed to 
display-buffer, display-buffer ignores the value.

I'm not 100% I did everything right, but I looked at 
gdb-display-buffer-other-frame-action for reference and verified the behavior 
of the change myself.
