One example where this is needed is updating the outline buttons
based on the changed text in a ts-mode buffer.

Either after-change-functions or jit-lock-function calls
outline--fix-up-all-buttons that uses treesit-outline-search
that requires the updated ranges.

I see that treesit-indent and treesit-indent-region
explicitly calls treesit-update-ranges at the beginning.
Is it how treesit command are intended to update ranges
for themselves?  It would be inefficient to call
treesit-update-ranges in treesit-outline-search.
