Support markdown links preview in chat UI

[julien-nc]

Override NcRichText link resolving to support markdown links.

This currently produces a lot of warnings because the references prop of <NcRichText> is declared as Object but the implementation actually expects an array. I'll fix that in nc/vue.

Tested, looks good! Testing libraries left and right 🚀

Let's wait to merge that, I realized it was not avoiding the closing parenthesis. I think we need 2 regexps, one for plain URLs and one for markdown links. I'll do that later.

Or we need to strip stuff from the end? Like if the link is part of a sentence in brackets (like this https://test.com) or at the end of a sentence with a dot e.g. https://test.com.

The problem is that brackets are allowed in GET params. So why should we strip anything from (like that https://text.com?plop=lala) .
We can make the choice to not support trailing brackets (that should probably be url-encoded anyway. But how do we choose the list of characters that we strip? Most of them will be allowed in GET params. Not sure how to proceed here.
