Incorrect curl commands for import/export API Polices

[RusJaI]

Description:
In the APIM 4.2.0 documentation the provided url in the curl command is incorrect in operation policy import/export flows. (It should be operation-policies/ instead of policies and better if could describe the params as well) Please check this in other 4.x docs as well.
