Add unit tests for Update method in OrganizationInviteLinksController

- Implemented multiple test cases for the Update method, covering scenarios such as successful updates, handling of non-existing invite links, and validation errors for allowed domains.
- Ensured comprehensive coverage of the Update functionality to validate correct behavior and response models in various conditions.
