No support for stake script rewards

[klntsky]

Describe what the problem is?

It looks like Ogmios only support querying stake rewards for PubKey hashes, there's no ScriptHash support:

1. ogmios/server/src/Ogmios/Data/Json/Query.hs

   Line 904 in 7a03960

   credentials <- decodeCredentials obj

2. ogmios/server/src/Ogmios/Data/Json/Query.hs

   Line 1589 in 7a03960

   fmap (Ledger.KeyHashObj . Ledger.KeyHash) . decodeHash

3. https://github.com/input-output-hk/cardano-ledger/blob/9a25a43f3970941a2cd64029f7ce667b48832635/libs/cardano-ledger-core/src/Cardano/Ledger/Credential.hs#L73

What should be the expected behavior?

We need this kind of query to work with script hashes as well for CTL.

Indeed, as indicated in the note here:

ogmios/server/src/Ogmios/Data/Json/Query.hs

Line 1578 in 7a03960

-- TODO: Makes it possible to distinguish between KeyHash and ScriptHash

So, bech32 will likely come at the rescue here.
