Fix noise settings

[aguinot]

Fix the noise settings to match what was used to generate the current ref image. This should fix the CI test

I just tested locally and get a discrepancy --

>       np.testing.assert_allclose(output_data, reference_data, rtol=RTOL, atol=ATOL)
E       AssertionError: 
E       Not equal to tolerance rtol=0, atol=0.1

tests/test_end_to_end.py:71: AssertionError

it's pretty close in most cases, but 74 pixels are off

Do we still want to merge these changes? If so, I think we need to update the branch and then run the Make Reference Image workflow

[aguinot]

Now the main branch run but the created image does not contain noise. I guess it is up to us to decide if we want the noise to be included in the reference image. But as you said this will not fix anymore and will require to re-generate the ref image.
