docs: Record which online stores support versioned reads 
The versioning reference still said version-qualified reads were SQLite-only.
Seven stores support them now, so the page understated the feature by six
stores before this branch and by seven after it. The list is taken from
OnlineStore._is_versioned_read_supported, which is what actually decides.

## Online Store Support

{% hint style="info" %}
**Currently, version-qualified online reads (`@v<N>`) are only supported with the SQLite online store.** Support for additional online stores (Redis, DynamoDB, Bigtable, Postgres, etc.) will be added based on community priority.
**Version-qualified online reads (`@v<N>`) are supported on the SQLite, PostgreSQL, MySQL, Redis, DynamoDB, Milvus, FAISS and Cassandra online stores.** Support for the remaining online stores will be added based on community priority.

If you need versioned online reads for a specific online store, please [open a GitHub issue](https://github.com/feast-dev/feast/issues/new) describing your use case and which store you need. This helps us prioritize development.

## Known Limitations

- **Online store coverage** — Version-qualified reads (`@v<N>`) are SQLite-only today. Other online stores are follow-up work.
- **Online store coverage** — Version-qualified reads (`@v<N>`) are supported on SQLite, PostgreSQL, MySQL, Redis, DynamoDB, Milvus, FAISS and Cassandra. The remaining online stores are follow-up work.
- **Offline store versioning** — Versioned historical retrieval is not yet supported.
- **Version deletion** — There is no mechanism to prune old versions from the registry.
- **Cross-version joins** — Joining features from different versions of the same feature view in `get_historical_features` is not supported.
