CIP-0005 | Add governance vote key prefix

[gitmachtl]

• add 'gov_sk' as the prefix for a governance_signing/secret_key
• add 'gov_vk' as the prefix for a governance_verification/public_key

can be used f.e. with CIP-0036 to export vote(governance)-public-keys from wallets for delegation purpose in a format like: gov_vk12a6cjyf98a4nrhe2slqsavy29jdcg5rk3jud6rfh3kfl0shzyrcqkwgdzk

I can see how this would be needed as long as @KtorZ agrees, and as long as gov_ as a prefix is neither too general nor too specific (@SebastienGllmt ?)

For example, the keys that will be derived from the path m / 1694' / 1815' / account' / chain / address_index link will be marked like

{
  "type": "PaymentExtendedVerificationKeyShelley_ed25519_bip32",
  "description": "Governance Verification Key",
  "cborHex": "5840c2cd50d8a231fbc1444d65abab4f6bf74178e6de64722558eeef0b73de293a8a3e852c83508c7d300593734ec84351c3d1916d00571a57f3c0f63a7c972eb299"
}

with "Governance Verification Key" or "Governance Hardware Verification Key" in the description (unclear until now if the type will be changed to GovernanceExtendedVerificationKeyShelley_ed25519_bip32 too).
So tools like cardano-hw-cli or the SPO scripts will follow that description. and it makes sense imo to just use an overall 'gov / governance' naming for such keys. not limiting it to only voting purposes.

Looks sensible to me!

Sensible change imo
