Components v2: use valid JSON examples

[hackermondev]

None of these components have proper JSON examples. I'm not sure why, but I'm assuming it's not intentional.

I'd assume it was done that way to show that it belongs in payload's component field, but that isn't the main bit being demonstrated in the example. These updated ones are now showing examples of the full payload_json but are missing the component v2 flag, so if anything I think these are more wrong based on that. If it were to change, I think it'd make most sense to remove the components field entirely and just give the component itself (given that's what the example is supposed to be showing), but its fine as is imo

@leymbda I think changing the examples just to show the inside of the components array makes the most sense here. I now understand what he was trying to do with the partial, but just having the dangling components field is confusing.
