bug#66988: 30.0.50; treesit-forward-sexp not working properly in js-ts-mode and tsx-ts-mode

[Loïc Lemaître]

Hi Emacs team,

Here the steps to demonstrate the bug :

1. Compile Emacs from master branch with tree-sitter support
2. Install javascript and tsx languages
3. Run Emacs
4. Create a new buffer
5. Turn major mode to either js-ts-mode or tsx-ts-mode
6. Past the following content into the buffer:
(
  <div>
  </div>
);
7. Place point before opening parenthese
8. M-x forward-sexp (which will call treesit-forward-sexp)

=> New position is right after the semi-colon instead of being before 
the semi-colon.

Note that the bug disappear if the buffer content is changed for :
const component = (
  <div>
  </div>
);

But previous content, while not being very usefull, is valid JSX, as far 
as I know.
I use this syntax for unit test purpose, since it is very short.

Thanks !
