The recommended pruning parameter `--prune.r.older=2_000_000` prunes too many blocks to successfully sync an Eth2 client.

At the time of writing, we're at block 13411141. That means with the above prune parameter, recipes of blocks older than 11411141 are pruned. This misses some required blocks, as the deposit contract was deployed at block 11184524 (see option `--contract-deployment-block` from [here](https://docs.prylabs.network/docs/prysm-usage/parameters/))

Instead, use the new `--prune.r.before 11184524` option together with `--prune htc`
