debian med blend thermometer unrelated crux should probably be crux-toolkit

[Ben Tris <benattris@gezapig.nl>]

The removed package crux is unrelated to debian-med

https://tracker.debian.org/pkg/crux

At least crux is to be found

https://blends.debian.org/med/thermometer/

https://salsa.debian.org/med-team/crux

The packagelist only lists crux-toolkit (not on the thermometer page)

https://blends.debian.org/med/tasks/packagelist

Medical category I,ll try to keep up.
