AzureDevOpsDsc: Built module contain folder 'Classes'

[johlju]

We should remove the entry Classes from here:

AzureDevOpsDsc/build.yaml

Lines 5 to 9 in 8d43d12

	CopyPaths:
	- Classes
	- en-US
	- Examples
	- Modules

ModuleBuilder will add the classes automatically in the .psm1 file. Now they are duplicated in the folder Classes.
