Title of the page should be get through tdoc.plainTitle instead of doc.title

Actual behaviour :

The title of the page is not rendered correctly when containing scripted title or when translated, example :

Root cause :

https://github.com/xwiki-contrib/page-rights-viewer/blob/master/src/main/resources/PageRightsViewer/Code/Sheet.xml#L34

doc.title is used and is actually displaying the title as it is, without interpreting it in velocity.

Please consider using tdoc.plainTitle instead.
