     * Returns a document reference for the given document id.
     * The document id is an object that maps the primary keys of the collection (as defined in the Squid Console)
     * to their values. There are a few exceptions:
     * 1 - String document id is only supported for the `built_in_db` when a schema was not defined.
     * 2 - Not all the fields in the document id are required. If a field is not provided, it will be generated on the
     *     server once the document is created (if the integration supports it).
     * 3 - When a document id is not provided, it will be treated as an empty object or empty string.
     * 4 - When the document id is just a `string` and not provided (applies only for the `built_in_db`), it will be
     *    generated on the server.
     * 5 - If the collection in the `built_in_db` does not have a schema, the document id must be provided as a string.
     *
     * Examples:
     * ```typescript
     * // For a collection in the built_in_db that does not have a schema
     * const docRef = collectionRef.doc('my-doc-id');
     * const docRef = collectionRef.doc({id: my-doc-id'});
     *
     * // For a collection with a single primary key field called "id"
     * const docRef = collectionRef.doc({id: 'my-doc-id'});
     *
     * // For a collection with a composite primary key
     * const docRef = collectionRef.doc({id1: 'my-doc-id1', id2: 'my-doc-id2'});
     * const docRef = collectionRef.doc({id1: 'my-doc-id1'}); // id2 will be generated on the server if the integration
     * supports it
     *
     * // For a collection from the `built_in_db` without a defined schema when an id is not provided
     *  const docRef = collectionRef.doc(); // The id will be generated on the server
     * ```

     * @param docId The document id as an object for the different fields in the primary key or a string.
     * @returns A document reference for the given document id.
