bug#60087: 29.0.60; c++-ts-mode conflict with electric-pair-mode

[Eason Huang]

Hello Emacs dev team,

I found that the c++-ts-mode conflict with electric-pair-mode.
My build is based on commit a15cd55044c6bb4d4e9f9aec23b8b5b9cbcb38ac

May be the issue was introduced by this commit:
https://git.savannah.gnu.org/cgit/emacs.git/commit/?h=emacs-29&id=480f41c7deb4d3a45a862a5308950b35085f835d

I can confirm that Before the commit 480f41c7, It work well.

steps to reproduce:

1. emacs -Q, start Emacs
2. C-x, C-f ~/test.cpp, open any cpp file.
3. M-x c++-ts-mode, enable c++ tree-sitter support
4. M-x electric-pair-mode, enable electric-pair-mode
4. Type the following code in the test.cpp buffer.
```
#include <
```
you will the the result as below:
```
#include <<
```

expected result is:
```
#include <>
```
