Notebook title: GLM: Poisson Regression Notebook url: https://www.pymc.io/projects/examples/en/latest/generalized_linear_models/GLM-poisson-regression.html

Issue description

# code, cell 18
inf_fish_alt = model.fit()

short Error:

TypeError: You are calling an Aesara function with PyTensor variables.
Starting with PyMC 5.0, Aesara was replaced by PyTensor (see https://www.pymc.io/blog/pytensor_announcement.html).
Replace your import of aesara.tensor with pytensor.tensor.
