git-remote-mediawiki: fix encoding issue for UTF-8 media files

When a media file contains valid UTF-8, git-remote-mediawiki tried to be
too clever about the encoding, and the call to utf8::downgrade() on the
downloaded content was failing with

Wide character in subroutine entry at git-remote-mediawiki line 583.

Instead, use $response->decode() to apply decoding linked to the
Content-Encoding: header, and return the content without attempting any
charset decoding.
