audio/fasttracker2: Update to 1.92

Changes since 1.91:

v1.92 - 20.12.2024
- Further improvement to the tracker scope interpolation (interpolation
  is centered around the current sample point now). This is barely noticable,
  but I wanted to fix it anyway.
- Added a config option in Config->Miscellaneous for enabling the original
  FT2 about screen (feeling nostalgic?).
- Did some very minor edits to the FT2 help text
