Fix: (org-ql--define-query-preamble-fn) Pcase pattern for Emacs 30

Now all tests and lints pass on Emacs versions 27.1-29.4.  But on the
current Emacs snapshot build used in CI, Buttercup is hanging
indefinitely, which may be the same problem that led Guix to disable
the tests in
<https://git.savannah.gnu.org/cgit/guix.git/commit/gnu/packages/emacs-xyz.scm?id=3add97c7761e6c58a1d7405f417a49dda5f0a742>.
But I've no way of knowing whether that's a problem in org-ql (seems
unlikely), Emacs snapshot, or Buttercup.  It would be nice to solve
this before Emacs 30.1 is released, but I don't know how to peer
inside Buttercup to find out what it's hanging on.

Fixes #433.
