Metrics exporter calls ancient /eth/v1/beacon/blocks/{block_id} api

[nflaig]

When running Kurtosis with the following setting

ethereum_metrics_exporter_enabled: true

I can see a lot of errors due to the exporter calling /eth/v1/beacon/blocks/{block_id}.

We have removed this api more than 6 months ago from Lodestar and it's not part of the latest beacon api spec release given those were removed almost 3 years ago ethereum/beacon-APIs#218 there.

I would be surprised if other clients still support this api, likely just nobody noticed these errors before but I know that all clients support getBlockV2 so it's probably best to start using that api instead.
