bug#56535: 28.1; `no' and `no-ding' values for isearch-wrap-pause option (since Emacs 28.1) not working as documented

[Arun V <arunlalv04@gmail.com>]

When I set the isearch-wrap-pause option to `no' or `no-ding', it
still displays "Failing I-search backward" on entering a non-matching
character. I still have to press C-r again to wrap around. This is the
same behaviour as having set the value of isearch-wrap-pause to t.
