textproc/hs-commonmark-extensions: Update to 0.2.3.3

0.2.3.3
* Fix definition_lists extension (#96). We were not properly consuming
  indentation in definitions, which caused problems when the definitions
  themselves contained lists.

0.2.3.2
* Update lower version bounds for commonmark (#93, David Thrane
  Christiansen).

0.2.3.1
* math extension: don't fail when display math contains embedded inline
  math. See jgm/pandoc#7942.
* Make math parsing more sophisticated. Count embeddings inside {..}, since
  math can contain e.g. \text{...} which itself contains math delimiters.
* Small improvement in pipe table parsing. The old parser failed on some
  edge cases with extra whitespace after pipes (which we should just
  ignore).
* fancy_list extension: improve list type ambiguity resolution (#89).
