Add option to disable talking to the internet on `import dace`

**Describe the bug**
If dace is imported in a jupyter notebook it tries to talk to the internet. https://github.com/spcl/dace/blob/b54a3c61baf8f0c696718ac451bb707929c33ee9/dace/jupyter.py#L70

Recently GT4Py added testing jupyter notebooks with Github actions which fail frequently in this check, probably because of some network instabilities in the runners.

I would propose to add, at least, the option to disable trying to access the internet.
