fix(code-block): handle unknown languages better

[nperez0111]

This resolves a bug where if a language is a language that is not within supportedLanguages, it would throw an error rather than silently letting you continue to use it as a plaintext code block

nice. does it make sense to log a warning? it's a bit suspicious when a block has a language that doesn't have a highlighter, right?

The user can add a block like that by typing ```anytext

So, I don't think it is on the dev at that point. I like the fallback to no highlighting at all
