Added note about minimum required cluster version for upgrades to 3.x.x.

Description

For a v2->v3 rolling upgrade to work smoothly, the minimum required version is v2.19.0.
This is not currently not listed in the page, so people (like myself) can try rolling upgrade e.g., from 2.18.0 to 3.2.0 which fails.
More info: opensearch-project/OpenSearch#19375

Version

3.0.0
