Fix nats-jetstream scaler to use account ID instead of name

[cmay-zh]

NATS API uses account ID to filter by account (as confirmed by NATS team).

Current checks causes an issue when account ID and name are different. Updating the checks to use account ID instead.

To replicate issue, create a NATS account with name different from ID like below

  "account_details": [
    {
      "name": "platform",
      "id": "AABMFGXW62SSPMCCGFFOP7HFDFFBJWFAM3MC66OM2EHJDZS5CWTSHCWA",
      "memory": 0,
      "storage": 285,
      "reserved_memory": 0,
      "reserved_storage": 18446744073709551615,
      "accounts": 0,
      "ha_assets": 0,
      "api": {
        "total": 7088,
        "errors": 0
      },

Create nats-jetstream ScaledObject, check logs and find error “scaler”: “natsJetStreamScaler”, “error”: “leader node not found for consumer”

Hello
I get your requirement, but this is a potential breaking change that we must avoid. Mi proposal is to add an extra parameter like 'accountID' to provide the value, and then use it to match account ID instead of account name. WDYT?
If this new parameter is mutually exclusive with the current account, it should work without any incident
