New bech prefixes for governance keys

Just in case it got lost between all the other news :sunglasses:

for the upcoming change in the governance/catalyst voting, a new bech prefix for public/private keys was defined.

private/signing key prefix: gov_sk
public/verification key prefix: gov_vk

it got merged into CIP-0005 already, so you can start using this prefix for any kind of governance public/private keys…
