Subject: bug#72068: show-paren-mode does not match Chinese parentheses correctly

Reproduce steps:
1. Emacs -Q
2. M-x eval-expression
```
(progn
(setq cursor-type 'bar)
(show-paren-mode 1))
```
3. Paste the following text in any .el file
```
(英文括号)
(英文 括号)
(中文括号)
(中文 括号)
```
4. Place the cursor at the first position (or last position) of each line.
The expected behavior: All of the four lines above match and highlight
correctly
The actual behavior: The 4th line mismatched. Note the middle SPC character.
P.s.
1. This issue only occurs in lisp-like modes. It is OK in c-mode and
python-mode.
2. 【】「」『』have the same problem. They are also commonly used in lisp comment.
3. A simple investigation found that it may be related to `scan-sexps` or
syntax-table, because `(scan-sexps outside dir)` in the
`show-paren--default` returns the wrong value in the 4th case.
4. More screenshots and test code can be found in
https://emacs-china.org/t/show-paren-mode/15160
Emacs 29.3 on Windows.
Thanks.
Best regards
