[BUG] Schema validation fails to prevent invalid 'until' property in retry configuration

[nathaliellenaa]

What is the bug?

The schema validation is not preventing the use of an invalid until property in the retry configuration.

How can one reproduce the bug?

retry:
  count: 3
  wait: 10000
  until:
    - path: payload.state
      equal: COMPLETED

No error is thrown, despite until not being a valid property in the retry schema.

What is the expected behavior?

The schema validation should reject the configuration and throw an error, indicating that until is not a valid property in the retry configuration.
