Don't transform quotes in Markdown

[silverwind]

Quotes outside of code blocks (example) are currently transformed to U+201C Left Double Quotation Mark and U+201D Right Double Quotation Mark. I think this transformation is generally unwanted and confusing because it alters the original content, so I'd like to see it removed. GitHub also does not do this.

@silverwind keep the quotes as-is?

[silverwind]

@bagasme yes that would be my preference. The less "magic" the better.

[guillep2k]

I agree, but maybe make it optional for wikis.

Changing the default now is difficult to necessarily sign off. However, #11047 shows the way to do it.

Add a new frontmatter part:
