[openapi] - Errors in Documentation

[AliSot2000]

I found some issues in the openapi.json

{
  "version": "2024.9.5",
  "engine": "NOWEB",
  "tier": "PLUS",
  "browser": "/usr/bin/chromium"
}

Errors found in the Documentation that caused malformatted code:

• WebhookConfig: Expects for Events array<any>. It should be Event
• SessionInfo.engine: Is Optional[str]. I would assume it is Supposed to be the Enum Engine. The actual value is {'engine': Engine} I'd be in favor of removing the wrapper and just putting the engine in there.
