fix: Fix snippets being placed leftwards of where they should be

Snippet bits were being escaped before placing snippets, shifting snippets leftwards. Snippets were also being shifted leftwards on files with CRLF line endings since they were placed done after the Unix -> DOS line ending conversion.

Hoping this fixes all of the little bugs related to snippet rendering 😅
