PNRDetector example in the intro page failed

[sylviemonet]

Before posting a bug report

• I have searched exisisting GitHub issues to make sure the issue does not already exist.

Expected behavior

results = Gaussian(2) << PNRDetector(efficiency = 0.9, modes = [0]) results[0] # unnormalized dm of mode 1 conditioned on measuring 0 in mode 0 results[1] # unnormalized dm of mode 1 conditioned on measuring 1 in mode 0 results[2] # unnormalized dm of mode 1 conditioned on measuring 2 in mode 0

Actual behavior

NotImplementedError: Function convolution not implemented for backend numpy.

Reproduces how often

Everytime

Additional information

I started a new virtual env (only with python=3.11 and pip install mrmustard and pip install Jupyter) and try to test all examples in the intro page.
