Add the Linked field to more projects

The Linked field, which is now automatically updated by [Bot] Arisa to the number of duplicate links on projects when it exists, is quite useful for tracking parents or finding commonly reported issues.

Currently, it only exists on MC, MCL and MCPE.

It would be helpful if that field could also be added to all other projects, so that it can be updated there in the future as well.
