Revise "Handle ApiVersions requests #pv1" (stage 5)

[TropicolX]

Removed placeholder text and updated instructions for the ApiVersions stage.

---

Note

Expands stage_descriptions/base-05-pv1.md with a detailed ApiVersions v4 response spec, example hex, test command, and validation criteria (including message_size).

• Docs (stage_descriptions/base-05-pv1.md):
  • Add recap of the ApiVersions API with links to request/response inspectors.
  • Specify v4 response body structure, including error_code, api_keys (compact array with tagged fields), throttle_time_ms.
  • Require entry for API key 18 with min_version 0 and max_version 4.
  • Provide example hex-encoded response and emphasize correct message_size calculation.
  • Add test instructions: command to send a sample request, breakdown of request header, and response validation checks (matching correlation ID, error_code 0, required API key entry, no trailing bytes).
  • Clarify notes: tester uses v4 and validates the first 4 bytes (message_size).
