Update testnet configs, change on-disk format (#1799)

## Issue Addressed

- Related to #1691

## Proposed Changes

- Add `DEPOSIT_CHAIN_ID` and `DEPOSIT_NETWORK_ID` to `config.yaml`.
    - Pass the `DEPOSIT_NETWORK_ID` to the `eth1::Service`.
- Remove the unused `MAX_EPOCHS_PER_CROSSLINK` from the `altona` and `medalla` configs (see [spec commit](2befe90032 (diff-efb845ac2ebd4aafbc23df40f47ce25699255064e99d36d0406d0a14ca7953ec))).
- Change from compressing the whole testnet directory, to only compressing the genesis state file. This is the only file we need to compress and *not* compressing the others makes them work nicely with git.
    - We can modify the boot nodes, configs, etc. without incurring an eternal binary-blob cost on our git history.
    - This change is backwards compatible (i.e., non-breaking).
