Tracker online developer documentation is out of date

The documentation at developer.gnome.org stopped being updated after the Tracker 2.0.x series:

• https://developer.gnome.org/libtracker-control/stable/
• https://developer.gnome.org/libtracker-miner/stable/
• https://developer.gnome.org/ontology/stable/
• https://developer.gnome.org/libtracker-sparql/stable/

This is due to an infrastructure issue: Infrastructure/library-web#50
