textproc/hs-pandoc-types: Update to 1.23.1

[1.23.1]

  * Restore toJSONFilter instance for pure `a -> [a]`.
    This went missing after my ill-considered revision to #105,
    commit 183af9d9f1066be974ac55fd23a4c985999d3ce8 . See jgm/pandoc#8976.

  * Generalize ToJSONFilter instance. Previously a pure function `a -> a`
    could only be promoted to a filter in IO. Now we allow it to work with
    any instance of MonadIO.  (This adds to #105.)

  * Allow bytestring 0.12.

[1.23.0.1]

  * Allow aeson 2.2.

  * Remove dependency on string-qq (recbecca skinner).
