CommonMark code block class names

[remyrylan]

This is a very simple fix to follow the CommonMark spec for code blocks:
https://spec.commonmark.org/0.27/ Example: https://spec.commonmark.org/0.27/#example-109

Right now Marked defaults to lang- for fenced code blocks, which as far I understand it, is legacy from Highlight.js. By enforcing the CommonMark standard developers will be able to leverage other CommonMark tools when using output from Marked.

I'll look into the failing tests later, Travis appears to be down at the moment (rendering only a blank white page).

looks like the tests /test/new/gfm_code.html and /test/new/gfm_code_hr_list.html uses lang-. You can change them to use language-

and example 111 and 113 can be taken out of shouldPassButFail in /test/specs/commonmark/commonmark-spec.js

marked/test/specs/commonmark/commonmark-spec.js

Line 158 in 579f7bf

var shouldPassButFails = [93, 95, 96, 97, 101, 102, 106, 108, 111, 112, 113];

@UziTech Updating right now. Pushing a new commit within 5 mins. Sorry I missed them earlier.

[remyrylan]

Ok, new commit pushed. Tests pass for me locally. Thank you so much for the help and super fast response, @UziTech!

[UziTech]

No problem. Thanks for the PR 💯

[UziTech]

Can you revert marked.min.js that will be updated automatically when the PR is merged

[UziTech]

this parameter should still be --lang-prefix since that is what the option is called

[remyrylan]

Fixing everything now, pushing in a few moments. Will undo the changes to marked.min.js in my other PR as well.

[UziTech]

this should also be --lang

[remyrylan]

Ok all changes in and fixed the Git history.

[UziTech]

Nice 🎉 Thanks again 🥇

This will be a breaking change but our next release has several breaking changes so good timing, thanks! 👍
