fix:Phase2 onnx model with added Softmax layer

[uttiyasarkar]

Following the presentation in HLT upgrade meeting here dated 03.06.2025, we spotted a bug on the current Phase-2 DeepJet model for b-tagging here.
It has a missing Softmax layer which makes the final DeepJet scores wrong.
The issue has been addressed and the model is modified with the additional Softmax step in the correct place. This model is validated and results are shown in the above mentioned presentation.

This PR includes:

• The fixed DeepJet onnx model with Softmax layer included.

IIUC the file RecoBTag/Combined/data/DeepFlavourV02_PhaseII/DeepJet_retraining_phase2_new_inputs.onnx is bugged.
I think we should remove it from the release. Do you agree?
