Update semantic-mediawiki

semantic-mediawiki is compatible with mediawiki 1.36, but outputs a lot of deprecation
warnings. This was fixed in
https://github.com/SemanticMediaWiki/SemanticMediaWiki/pull/4195
but no relase has been made as of now. This change will be in release
3.2.4 or 4.0.0, at which point this line can be removed.
