Remove unnecessary replace_in_variable (#11424)
# Description `Expression::replace_in_variable` is only called in one place, and it is called with `new_var_id` = `IN_VARIABLE_ID`. So, it ends up doing nothing. E.g., adding `debug_assert_eq!(new_var_id, IN_VARIABLE_ID)` in `replace_in_variable` does not trigger any panic. # User-Facing Changes Breaking change for `nu_protocol`.
