Description

Add syntax highlighting to thumbnails/previews of code files.

QSyntaxHighlighter does exist, but it seems to be meant more for being used by other Qt widgets, and we would need to specify (or find) syntax highlighting rules for every language we wanted to support. I would say it would make more sense to use a python library for treesitter, like https://github.com/tree-sitter/py-tree-sitter
