New container julia 1.9.4

[vnm-neurodesk]

There is a new container by @stebo85, use this command to test:

bash /neurocommand/local/fetch_and_run.sh julia 1.9.4 20240405

If test was successful, then add to apps.json to release:
https://github.com/NeuroDesk/neurocommand/edit/main/neurodesk/apps.json

Please close this issue when completed :)

goal is to use this as a testbed to expose the julia environment to the jupyter kernel outside
