Add workflows and training to tool json/tsv

[paulzierep]

The tool file is used to populate the RESC https://github.com/research-software-ecosystem/utils/blob/main/galaxytool-import/galaxytool-import.py

This is used in a new project to create a RSE Metadata Explorer of the complete RESC: https://hash-bash.github.io/StudyProject/
For this it would be great if the tool view could show the Galaxy workflows and trainings where the tool is used as well.
We got workflows and training in separate files, but we could add an additional step that adds workflows and training in two additional columns of the tool json/tsv.
