Support "dtx" vim key combination when "x" is immediately to the right of the cursor (#6830)

Closes #4358

The bug originates on this line:
5db7e8f89e/crates/vim/src/motion.rs (L451)

- When running "dtx" on "ˇabcx", the range to delete is 0 -> 2 ("abc")
- When running "dtx" on "abˇcx", the range to delete is 2 -> 2 ("c"), so
`new_point == point` and the function incorrectly returns `None` and "c"
is not deleted
- We need to disambiguate between the "not found" case and the "found
immediately to the right" case
- This bug does not apply to the backwards case ("dTx")

Release Notes:
- Fixed "dtx" vim key combination when "x" is immediately to the right
of the cursor (#4358)
