Title: Syntax highlighting (XML) for Zope .zcml and .pt files

Various Python development communities (https://github.com/plone, https://github.com/collective, others) and developers on github using Zope page templates (.pt) and Zope Configuration Markup Language (.zcml) would greatly benefit from syntax highlighting of files with these extensions as XML. languages.yml is updated and tests pass without regressions.
