Don't show error messages for prismjs missing languages

[iRoachie]

💥 Proposal

Currently, it's possible to use usePrism: true to set prismjs as the syntax highlighter for all languages. However when a language that prismjs doesn't support is used, the errors are logged to console. Personally think this could be done much better.

 Error: Cannot find module 'prismjs/components/prism-html.min'

@endiliey I'd like to take this up. Do you have something in mind, of how we can do better here? It looks like the error is thrown from here

require(`prismjs/components/prism-${language}.min`);

inside renderMarkdown.js if I'm not wrong. Also, based on the exact error mentioned in this issue, it looks like the term language-html is unsupported by prismjs. Would it be useful to add an exception for that, because to me it seems like a reasonable expectation to fallback to language-markup when the user specifies language-html instead.

[endiliey]

Instead of throwing the error stack. Lets log that the language is not supported.

Any other idea is welcomed
