bug#65411: 29.1; setopt of xref-after-jump-hook gives warning

[Howard Melman]

In Emacs 29.1 should I be able to do this:

    (setopt xref-after-jump-hook '(reposition-window xref-pulse-momentarily))

When I do in my init and then use xref-find-definition I get this warning:

    ⛔ Warning (emacs): Value `((reposition-window xref-pulse-momentarily))' for 
`xref-after-jump-hook' does not match type hook

(FYI, I'm doing this in the macport and haven't tried it yet
in GNU Emacs)

I thought I could because I copied the format from xref.el:

        (defcustom xref-after-jump-hook '(recenter
                                          xref-pulse-momentarily)

and if instead I do this:

        (add-hook 'xref-after-jump-hook 'reposition-window)
        (add-hook 'xref-after-jump-hook 'xref-pulse-momentarily 'after)

and check the value of xref-after-jump-hook it is:

    (reposition-window xref-pulse-momentarily)

which is what I want but confuses me why recenter from the
default value isn't there.  I don't see xref-after-jump-hook used
anywhere else in my init or installed packages.
