Merge #6229: fix: creditOutputs in AssetLock tx json output should …

…be an array of objects, not debug strings

9876c2d docs: add partial release notes (UdjinM6)
b330318 refactor: drop circular dependency (UdjinM6)
e54fe42 refactor: use `key_to_p2pkh_script` in more places (UdjinM6)
3ed6246 test: check `creditOutputs` format (UdjinM6)
ba0e645 fix: `creditOutputs` in AssetLock tx json output should be an array of objects, not debug strings (UdjinM6)

Pull request description:

  ## Issue being fixed or feature implemented
  Txout-s in `creditOutputs` for AssetLock txes should be shown the way txout-s are shown in other places. We should not be using debug strings there.

  Example: `getrawtransaction 50757f651f335e22c5a810bd05c1e5aac0d95b132f6454e2a72683f88e3983f3 1`

  develop:
  ```
    "assetLockTx": {
      "version": 1,
      "creditOutputs": [
        "CTxOut(nValue=0.01000000, scriptPubKey=76a914cdfca4ae1cf2333056659a2c)"
      ]
    },
  ```

      "version": 1,
      "creditOutputs": [
        {
          "value": 0.01000000,
          "valueSat": 1000000,
          "scriptPubKey": {
            "asm": "OP_DUP OP_HASH160 cdfca4ae1cf2333056659a2c8dc656f36d228402 OP_EQUALVERIFY OP_CHECKSIG",
            "hex": "76a914cdfca4ae1cf2333056659a2c8dc656f36d22840288ac",
            "address": "yf6c2VSpWGXUgmjQSHRpfEcTPsbqN4oL4c",
            "type": "pubkeyhash"
          }
        }
      ]
    },
  ```
  kudos to @coolaj86 for finding the issue

  ## What was done?
  Change `CAssetLockPayload::ToJson()` output to be closer to [`TxToUniv()`](https://github.com/dashpay/dash/blob/develop/src/core_write.cpp#L262-L272)

  NOTE: `refactor: use key_to_p2pkh_script in more places` commit is a bit unrelated but I decided to add it anyway to make it easier to follow assetlock creation vs getrawtransaction rpc check.

  ## How Has This Been Tested?
  Try example above, run tests

  ## Breaking Changes
  RPC output is different for AssetLock txes
