devel/difftastic: update to 0.35.0

0.35 (released 2nd September 2022)

Diffing
 - Difftastic now fixes sliders in more cases, producing better diff results.

Parsing
 - Difftastic will now autodetect files in UTF-16-BE and UTF-16-LE.
   Previously it required files to be UTF-8.
 - Added support for Makefiles.
 - Fixed an issue with HCL language detection on .workflow files. Fixed an
   issue with Makefile language detection.

Command Line Interface
 - Fixed terminal width detection when only stderr is a TTY (e.g. when using
   difftastic with git). This was broken in 0.34.
 - Added an option --list-languages which reports all the languages supported,
   along with the extensions associated with them.
