ValueError when setting zmin, zmax for rgb image

There seem to be a validation error bug for setting zmin, zmax for rgb images. It appears the validation code expects a tuple or list of size 4 ( as would be the case for rgba) and not size 3 as should be the case for rgb.

im= np.random.randint(256,size=(50,50,3),dtype=np.uint8)
fig = go.Figure(go.Image(z=im,colormodel='rgb',zmin=[10,10,10],zmax=[100,100,100]))
fig.show()

Results in the following error:

File "C:\Users\NA\Anaconda3\lib\site-packages_plotly_utils\basevalidators.py", line 283, in raise_invalid_val

valid_clr_desc=self.description(),

ValueError:
Invalid value of type 'builtins.tuple' received for the 'zmax' property of image
Received value: [100, 100, 100]

The 'zmax' property is an info array that may be specified as:

* a list or tuple of 4 elements where:

(0) The 'zmax[0]' property is a number and may be specified as:
- An int or float
(1) The 'zmax[1]' property is a number and may be specified as:
- An int or float
(2) The 'zmax[2]' property is a number and may be specified as:
- An int or float
(3) The 'zmax[3]' property is a number and may be specified as:
- An int or float

Comece reproduzindo o exemplo fornecido de NumPy e go.Image com um array RGB e valores de zmin/zmax de comprimento três. Rastreie a validação da propriedade da imagem que gera o ValueError e compare-a com o tratamento de RGBA. A tarefa estará concluída quando os limites RGB forem aceitos e a validação existente de RGBA continuar correta.
