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

首先，使用長度為三的 zmin/zmax 值和 RGB 陣列重現提供的 NumPy 和 go.Image 範例。追蹤引發 ValueError 的影像屬性驗證，並將其與 RGBA 處理進行比較。完成標準是接受 RGB 限制，同時現有的 RGBA 驗證仍然正確。
