Remove eBook called The Elastic Observability guide for AWS

[alaudazzi]

We no longer maintain the eBook downloadable from Integrations product page => blog => Observability product page => eBook called The Elastic Observability guide for AWS (PDF format).

Identify the owner of this page https://www.elastic.co/observability/aws-monitoring and ask to remove the reference to the PDF.

@alaudazzi is there a product manager you work with that should sign off on the decision to remove this from the website?
