Description

Extends the index compatibility reference table on the Migrate or upgrade page to include all OpenSearch releases from 2.15.0 through 3.5.0, with their corresponding Lucene versions.

The table previously stopped at OpenSearch 2.14.0 (Lucene 9.10.0). This PR adds:

Lucene version OpenSearch versions
10.3.2 3.5.0, 3.4.0
10.3.1 3.3.2, 3.3.1, 3.3.0
10.2.2 3.2.0
10.2.1 3.1.0
10.1.0 3.0.0
9.12.3 2.19.5, 2.19.4
9.12.2 2.19.3
9.12.1 2.19.2, 2.19.1, 2.19.0
9.12.0 2.18.0
9.11.1 2.17.1, 2.17.0, 2.16.0
9.10.0 2.15.0 (added to existing row)

Verification

All Lucene versions were verified directly from the OpenSearch source repository by checking gradle/libs.versions.toml at each release tag. The Elasticsearch column uses em-dash (—) for the new rows since OpenSearch 2.15+ and 3.x have no corresponding Elasticsearch releases sharing the same Lucene version.

Cross-referenced against public Elasticsearch documentation to confirm no Elasticsearch versions share these Lucene versions.
