textproc/hs-commonmark-pandoc: update to commonmark-pandoc-0.2.2.3

## 0.2.2.3

- Avoid adding spurious extra data-pos attribute to wrapper
  Div (#159).

## 0.2.2.2

- Add wrapper="1" when we need to add Div or Span. This is needed for
  good round-tripping; a djot writer can see that this attribute
  was added and remove the wrapping, adding the attributes directly
  to the element.
