getL2Tips does not returned actual L1-finalized block on .finalized #13697
Description
In yarn-project/stdlib/src/block/l2_block_source.ts I found below code. I've also found #13569 , but it does not specifically state that it's going to also fix the getL2Tips - hence I created this issue. Sorry if it turns out to be a duplicate.
/**
* Identifier for L2 block tags.
* - latest: Latest block pushed to L1.
* - proven: Proven block on L1.
* - finalized: Proven block on a finalized L1 block (not implemented, set to proven for now).
*/
export type L2BlockTag = 'latest' | 'proven' | 'finalized';
