Can't make diff colorized when using Octo

[proivk]

Hello Community,

Please help with colorizing diff output when using ":Octo pr diff" or "Octo pr changes" (telescope view).
Both ways diff remains uncolorized.

diff --git a/.gitignore b/.gitignore

The diffs are shown with filetype = diff. You need a syntax of treesitter parser for diff files to colorized them
