Manual:MediaWiki_Git_Guide propose option 'Open in Book Creator' to create a user book under User:username/Books/ with a dedicated book creator banner on pages display. If I use 'Display the book' on this banner I reach Special:Book whic proposes a button to 'Preview with PediaPress' and this leads to the generated book => https://pediapress.com/books/setup/8934ced7cd88c0ebfa5f925249d425/
Cliking there for preview => On first pages "Git and Gerrit" see all markup tags "languages translate tvar..." are present in the printed book.
