docs(http): add output variables for dependsOn checks

[Copilot]

Added documentation for output variables available when using dependsOn to reference outputs from other checks by name.

Changes

• New subsection "Referencing Outputs from Dependent Checks" in the HTTP check reference
  • Documents all available output fields: outputs.<checkName>.json, code, headers, body
  • Includes type information and descriptions for each field
  • Links to request-chaining concept documentation
  • Provides example using existing fixture demonstrating token extraction from login response

Example usage pattern:

- name: get-profile
  dependsOn: [login]
  headers:
    - name: Authorization
      value: "Bearer $(.outputs.login.json.token)"
