rss_converter_instagram.com.xsl: update to new json format

The new Instagram homepage provides json data in a format different than
before, update the xsl to support it.

Unfortunately the data in the new format does not provide the
descriptions of the items, so use some placeholder values (URL, comments
count, likes count) to present at least something.
