DropSite example: support markdown

Browse Source 
If the mime data includes text/markdown, display it decoded in the QLabel,
and also display the raw markdown in the table below.  QLabel supports
markdown since 51cbd5288c85cb4de382cb23d6f5559c2b626126.

Ideally we should add proper support for markdown to QMimeData, but
it's too late to do that for Qt 5.

Pick-to: 5.15
