On your very first connection to each testnet, you'll be asked to
become a validator. Please consult our private repo for a Goerli
Eth1 private key that you can use for deposits.
Other changes:
* Added a simple wrapper ./connect-to-testnet script calling the
nims file in the correct environment. No extension was used to
make the command the same on Unix and Windows.
* Bumped a number of modules with fixes from this week
* `make testnet0` and `make testnet1` will no longer delete your
existing database. This is considered a more appropriate behavior
for testing forward sync.
