Since we stop supporting Theia as a built-in Che editor, we need to cleanup che-devfile-registry and don't generate devworkspaces with che-theia editor (in devspaces repo)
Describe the solution you'd like
Remove generation of devworkspaces + che-theia editor
Remove information about devworkspaces+che-theia from the index.json
