fix: change products and powerups type in organization struct

[kolaente]

It looks like Trello changed this from a string value to an integer. I searched around in their api docs but couldn't really find anything about this so I just assumed int (not uint, int64, etc).

Before this patch, I got an error message like this:

JSON decode failed on https://api.trello.com/1/organizations/<uuuid>
{"id":"uuuid","name":"lorem-ipsum","displayName":"Lorem Ipsum","desc":"","descData":{"emoji":{}},"url":"https://trello.com/w/lorem-ipsum","website":"http://example.com/","teamType":null,"logoHash":"affffe","logoUrl":"https://trello-logos.s3.amazonaws.com/some-uid","offering":"trello.business_class","products":[110],"powerUps":[110]}: json: cannot unmarshal number into Go struct field Organization.products of type string

Hey, thanks for the contribution! I'm looking to do some updates soon and am happy to accept. I see there is test coverage over this type already, but the tests all had an empty array for powerUps. Would you mind adding tests with realistic data?

Added some, is that what you had in mind?
