fix: wrong pointer to "Nested Projections"

[patricebender]

The contents of this change are taken from the internal documentation where this has been available for quite some time now. It is still marked as beta feature, though.

what's wrong with that link?

what's wrong with that link?

I was looking for documentation on "Nested Projections" but the link behind "Nested Projections" points to a section "Postfix Projections" which is unrelated to the topic, or am I wrong with my assumption?

SELECT from bookshop.Books { /* POSTFIX PROJECTION */ }

SELECT from bookshop.Books { author { /* NESTED PROJECTION */ } }
