emacs-29 2baf9e107c: Fix shortdoc-tests failure with respect to regexp-opt-charset

[Mattias Engdegård]

branch: emacs-29
commit 2baf9e107c1d6f1c71f5804b6bd933d3f5d6a9ea
Author: Mattias Engdegård <mattiase@acm.org>
Commit: Mattias Engdegård <mattiase@acm.org>

    Fix shortdoc-tests failure with respect to regexp-opt-charset
    
    * test/lisp/emacs-lisp/shortdoc-tests.el (regexp-opt): Require.
    `regexp-opt-charset` is not autoloaded, and whether `regexp-opt` is
    preloaded is configuration-dependent.
