TextArea with textual[syntax] causes crash as of tree-sitter 0.25.0 #5976
Description
If I create a fresh build environment (in this case using rye):
rye init .
rye add "textual[syntax]"and run this code:
from textual.app import App, ComposeResult
from textual.widgets import TextArea
class EditApp(App[None]):
def compose(self) -> ComposeResult:
yield TextArea.code_editor(language="python")
if __name__ == "__main__":
EditApp().run()I get this crash:

AttributeError: 'tree_sitter.Query' object has no attribute 'captures'
If I then pin tree-sitter to anything less than 0.25.0:
rye add "tree-sitter<0.25.0"the code works again.
