Can't run lab 0 locally: ImportError: cannot import name 'ValidationInfo' from 'pydantic'

[mheiber]

Steps to Repro

clone this repo. I cloned today, and am at: 1041d44
cd ibm-quantum-challenge-2024/content/lab_0
ipython lab-0.ipynb

Tried on an M1 Mac with Python 3.11.5

Actual behavior

The line from qiskit_ibm_runtime import EstimatorV2 as Estimator
fails with ImportError: cannot import name 'ValidationInfo' from 'pydantic'.
This is the same error message as in Qiskit/qiskit-ibm-runtime#1577

Full error message:

Expected behavior

Runs without import errors
