Stream messages are actually items of a collection

[challet]

When using the stream function of the call builders, typescript thinks the messages passed to the onmessage callback are of type ServerApi.CollectionPage<TypeFromTheBuilderClass> when they are actually single items from the said collection.

Duplicate of #1040, not made at the exact same place though

@challet nice find! No idea why that hadn't been merged before 😢 I'm happy to merge yours but I'm curious if you think fixing it at the type source (EventSourceOptions) in #1040 is cleaner.

[challet]

I'm wondering it too :)
The result is exactly the same but here it keeps the EventSourceOptions as a generic interface, which might eventually be re-used somewhere else.

[challet]

However, inferring the type from the generic parameter is better than extracting it from how it is applied into the inner types.

I don't understand what's wrong with prettier here. It doesn't change a file by running it locally and the yarn command is made to only apply on './test/**/*.js'

Eh don't worry about it 👍
