Error thrown in shiki plugin

[Mister-Hope]

shiki will throw errors if getting unknown languages.

I would prefer to regard this as a bug, because you cannot force people to write markdown only contianing code blocks which shiki can parse.

No highlight should be the expected behaviour. @meteorlxy Any ideas?

Would this be fixed? I can open a pr which:

• add a list of language shiki supports
• precheck before passing to shiki

Any other ideas?

@meteorlxy Also please check this one.
