[Website]: Stack Monitoring

### Type of issue

Inaccurate

### What documentation page is affected

https://www.elastic.co/docs/deploy-manage/monitor/stack-monitoring/ece-ech-stack-monitoring

### What happened?

The section that states:

_The monitoring deployment and production deployment must be on the same major version, cloud provider, and region.

To avoid compatibility issues, ensure your monitoring cluster and production cluster run on the same Elastic Stack version. Monitoring clusters that use 9.x do work with production clusters that use the latest release of 8.x, but this setup should only occur when upgrading clusters to the same version._

This is incorrect as a monitoring cluster can function properly with a 9.x monitoring cluster and a 8.19.7 production clusters. This has been tested by a couple of Customer Architects.

If there is anything else you need - please let me know.
