Revert "[TO REVERT] Never run TMVA GNN tests and tutorials as unit tests"

[guitargeek]

This reverts commit baf092324e6e2a9301daff36a780cd064b232c2d.

We can either merge this as-is if the tests pass, or if they don't I'll close this PR without merging and open a GitHub issue about fixing these tests.

I am a bit worried about seeing the CI fully green on this PR but at the same time the sonnet module was not even the right one to check for as highlighted by https://github.com/root-project/root/pull/15605

[guitargeek]

Yes, the results of this PR are not valid. We'll have to see again tomorrow when the correct sonnet versions makes it into the CI images. In fact, one can see in the CI logs that the GNN tests didn't run.

It worked! Here the relevant output from alma9:

From my side this is ready to go. The more robust Python requirement configuration is something to follow up on in another PR, this one was just to revert the protection against red builds if the added Python packages would enable tests that don't work.
