Remove org.eclipse.mylyn.wikitext.ant and org.apache.ant dependencies from platform
Currently org.simantics.wiki.ui.feature
includes org.eclipse.mylyn.wikitext.ant
and therefore also org.apache.ant
.
We don't need Mylyn Wikitext Ant tasks, nor Ant for that matter.
Remove both from org.simantics.wiki.ui.feature
.
