adds a note about using aggregate with pagination

[angrykoala]

Adds a note about the behaviour of aggregate when using first and after pagination.

This PR also fixes two incorrect examples of aggregate

This is a draft PR until we confirm this is the desired behaviour

[rsill-neo4j]

The example doesn't show the optional arguments

do i understand correctly that you can add first and after but then the cursor does nothing? could we show that?

LGTM

Indeed, the cursor won't act on aggregates either, would you mean adding another example or changing what we have?

I'm worried that adding the cursor may make the behaviour harder to understand

maybe another query at the bottom, saying

"even if the query has a cursor, the result would still be the same.
[query listing]"

?

I've added a brief note, another example feels a bit much just to mention that after is also ignored
