TaskJuggler is not part of org mode. It is one of the packages in the
org contgrib package, which is now distributed via the nongnu elpa
repository (see https://elpa.nongnu.org/nongnu/).
I haven't used it in a long time and I don't think anyone is maintaining
it, so don't know how well it is working with current org versions.
