Review the Elastic OpenTelemetry compatibility and support docs and the ability to move the content to the Support matrix

The official [Support matrix](https://www.elastic.co/support/matrix#matrix_compatibility) currently refers users looking for EDOT compatibility to the [Elastic OpenTelemetry compatibility and support](https://www.elastic.co/docs/reference/opentelemetry/compatibility/index.html) docs (and, by extension, to the [Elastic OpenTelemetry compatibility and support for OTel Collectors](https://www.elastic.co/docs/reference/opentelemetry/compatibility/collectors) doc for the collectors).

We need to review if we can/want to move this content to the Support matrix and remove it from the docs to avoid having multiple sources of truth for Elastic product compatibility. Users should be able to find all the necessary compatibility information in the official Support matrix.

Start by comparing the official Support matrix with the Elastic OpenTelemetry compatibility and support docs, including the OTel Collectors page. Review whether the compatibility content can be consolidated without losing necessary information. Done means the compatibility information has one documented source of truth and any affected references or duplicate content are addressed.
