devel/difftastic: update to 0.37.0

0.37 (released 14th October 2022)
 - Added a Chinese translation: https://difftastic.wilfred.me.uk/zh-CN/
 - Improved runtime performance and memory usage (thanks to @QuarticCat).
 - Standalone . is now considered punctuation in the diff cost model, which
   improves diff results in some cases.
 - Updated to the latest tree-sitter parser for Swift.
 - Difftastic will now read a file from stdin if given - as a path argument.
 - Added an option --context to control the number of lines of context displayed.
 - --list-languages now respects the value of --color, whose default only uses
   styling when stdout is a TTY.
 - Fixed side-by-side display width when color is disabled (when piping
   difftastic stdout or with --color=never).
 - Fixed an issue with building on Windows with gcc.
