Adding sponsored brands and sponsored display to allowed ads_types for v3

[katja-d]

• So far only SPONSORED_PRODUCTS ads_type was included in assert for V3 of the API.
• Adding SPONSORED_BRANDS and SPONSORED_DISPLAY so we can migrate to V3 (V2 for both will be deprecated end of the month and capacity already reduced)

code-wise it looks correct, but cannot tell you if this works. Did you test it? :)

Yes tested locally :)
