Add programming language code to pages

Trying to add formatted and colorized programming language code to pages in Canvas.  Anyone know of a good way to do that?   Everything I find online uses both js and CSS to do that.  Is there an LTI for such a thing?  I heard from Canvas support that Github LTI is no more.

Pasting Code Into A Page  - LTIs in here no worky no more

Thanks.
