Lower tolerance of stale blobs on gossip

[michaelsproul]

Proposed Changes

Some peers are spamming old blobs from prior to finalization on gossip. We don't ban them quickly enough due to the high-tolerance peer penalty. This PR changes the penalty to a low-tolerance one.

From the peers that I spot-checked, all the spam seemed to be coming from Erigon/Caplin peers. I've communicated this to the Caplin devs, so new releases of Caplin shouldn't have this problem and won't suffer from by being banned by Lighthouse.

I've kept the gossipsub behaviour as Ignore rather than combining with the Reject block above. We are required to Ignore these blobs by the spec: https://github.com/ethereum/consensus-specs/blob/dev/specs/deneb/p2p-interface.md#blob-subnets
