🟡 Bigtable content-ref in docs links to mysql.md instead of bigtable.md

The bigtable entry in the online stores README links to mysql.md instead of bigtable.md. This is a pre-existing bug that was not introduced by this PR, but is visible in the changed file at docs/reference/online-stores/README.md:34.

Root Cause

At line 33-35 of docs/reference/online-stores/README.md:

{% content-ref url="bigtable.md" %}
[bigtable.md](mysql.md)
{% endcontent-ref %}

The url attribute correctly points to bigtable.md, but the markdown link text points to mysql.md. Depending on how the docs renderer processes this, users clicking the Bigtable link may be taken to the MySQL documentation page instead.

Impact: Documentation navigation error — users looking for Bigtable docs may land on the MySQL page.

(Refers to line 34)

## Functionality Matrix

There are currently five core online store implementations: `SqliteOnlineStore`, `RedisOnlineStore`, `DynamoDBOnlineStore`, `SnowflakeOnlineStore`, and `DatastoreOnlineStore`.
There are several additional implementations contributed by the Feast community (`PostgreSQLOnlineStore`, `HbaseOnlineStore`, `CassandraOnlineStore` and `IKVOnlineStore`), which are not guaranteed to be stable or to match the functionality of the core implementations.
There are several additional implementations contributed by the Feast community (`PostgreSQLOnlineStore`, `HbaseOnlineStore` and `CassandraOnlineStore`), which are not guaranteed to be stable or to match the functionality of the core implementations.
Details for each specific online store, such as how to configure it in a `feature_store.yaml`, can be found [here](README.md).

Below is a matrix indicating which online stores support what functionality.
