Warning handling in doc build is inconsistent

[pushfoo]

Our warning handling is inconsistent in how some warnings are treated as fatal errors.

Consistency checks within Sphinx produce warnings which get treated as errors, yet these errors from #2799's CI runs do not :

WARNING: No members parsed for 'arcade.types.numbers' with inferred path PosixPath('/home/runner/work/arcade/arcade/arcade/types/numbers.py'). Check & update yourconfig?
WARNING: No members parsed for 'arcade.sprite.enums' with inferred path PosixPath('/home/runner/work/arcade/arcade/arcade/sprite/enums.py'). Check & update yourconfig?
WARNING: No members parsed for 'arcade.sprite_list' with inferred path PosixPath('/home/runner/work/arcade/arcade/arcade/sprite_list/__init__.py'). Check & update yourconfig?
WARNING: No members parsed for 'arcade.texture' with inferred path PosixPath('/home/runner/work/arcade/arcade/arcade/texture/__init__.py'). Check & update yourconfig?
WARNING: No members parsed for 'arcade.texture_atlas' with inferred path PosixPath('/home/runner/work/arcade/arcade/arcade/texture_atlas/__init__.py'). Check & update yourconfig?

Hi @pushfoo ,

Can you assign the bug to me ?

I am new to OSS world, but not to the coding. I have 6 years of experience in IT industry.

Any help in the initial steps will be grateful.

With Regards,
Shekhar
