[component] Canvas

As a Workflow Developer,
I want to be able to use the native **Canvas** connector,
So that I can implement more complex integration use cases involving **Canvas**.

**References**

- Website: https://www.instructure.com/canvas
- Documentation: https://developerdocs.instructure.com/services/canvas

**Acceptance Criteria**

Implemented actions:

Implemented triggers

**Definition of Done**

- [ ] Unit/Integration tests
- [ ] Connection setup steps
- [ ] Guidejar tutorial for connection setup
- [ ] Documentation is generated and available

Start by reviewing the linked Canvas website and developer documentation to define the connector's supported actions, triggers, authentication, and connection setup. Then identify the project's existing integration patterns and add the required unit or integration tests, setup guidance, Guidejar tutorial, and generated documentation so every Definition of Done item is complete.
