update config with fields required at Electra

[rolfyone]

• added electra required fields
• added missing fields from late block reorg which are phase0
• added missing MAX_BLOBS_PER_BLOCK which should have been in deneb.

Left MAX_PAYLOAD_SIZE and removal of MAX_CHUNK_SIZE for #97
Left the electra fork epoch for #98

the REORG_* fields don't affect some clients as they haven't implemented late block reorg, but they should definitely be included in a config for the testnet. I'm not sure how we got away without MAX_BLOBS_PER_BLOCK for deneb.

Looks good!

Just for context: for Lighthouse we maintain our own copies of the testnet configs in our repo. We add the fields we need there, and we also have defaults for all the new fork fields so that we can maintain backwards compatibility with old configs that omit them. So, unless a param is changed from default, we don't really need it.

We're almost ready for late block reorg so not having these fields would definitely be sub optimal, but we can maintain our own config, it just seems pointless to have an incomplete testnet config on a repo supposed to house the testnet config...

Yeah, I agree we should merge it. Just wanted to give context for why LH isn't broken without these changes
