Add JSON editor UI hint to HTTP activities

This commit introduces a JSON editor UI hint to HTTP activities within Elsa Workflow. It includes creating new classes for a JSON editor options provider and a handler for this UI hint. Also, these additions are registered within the Elsa Workflow. The hint is applied to the 'RequestHeaders' and 'ResponseHeaders' input fields found in HTTP-related activity classes.
