[component] Intercom

As a Workflow Developer
I want to be able to use the native Intercom connector
So that I can implement more complex integration use cases where the connector is involved.

Website: https://developers.intercom.com/docs/references/introduction/

Acceptance Criteria

List of implemented actions:
1. create contact
2. get contact
3. send a message to contact

List of implemented triggers:
TODO

Definition of Done:

- [ ] Unit/Integration tests
- [ ] Documentation

Start with the Intercom developer reference linked in the issue and review how existing native connectors are structured in the repository. Implement the three listed contact and messaging actions, clarify the still-TODO trigger scope, and finish with unit or integration tests and documentation as required by the Definition of Done.
