fix(colorize): pass ZSH_COLORIZE_CHROMA_FORMATTER to cless function

The cless function did not forward the ZSH_COLORIZE_CHROMA_FORMATTER
environment variable to the colorize_cat preprocessor, causing colors
to render incorrectly on 256-color terminals when using chroma as the
syntax highlighter. ccat worked correctly because it passed the variable
directly.

Fixes #12650
