[Website]: Expand / Clarify the support matrix between ESF and Elasticsearch #3257
Description
Type of issue
None
What documentation page is affected
https://www.elastic.co/docs/reference/aws-forwarder
What happened?
The page mentions ESF Elasticsearch output supports ES 7.17.x onwards.
Can we expand the section to at least cover the last major versions (8.x, 9.x) and ideally add a back-reference to this page from https://www.elastic.co/support/matrix
According to the code, it's using the ES Client elasticsearch==7.17.12 and I do not expect it to use anything fancy apart from the _bulk.
