docs(methods): add agents.sessions method examples

Mirror the Python examples (slackapi/bolt-python-examples) for the two
agents.sessions methods, nested under agents/sessions/ to match:

- agents.sessions.rename    Rename an agent session.
- agents.sessions.setStatus Set an agent session's lifecycle status,
                            creating the session if needed.

Adds the two example classes, a per-family manifest (agent_view + the
agent bot events), and an "agents" section in the methods README.

Requires the agents.sessions methods in slack-api-client (adds via
slackapi/java-slack-sdk#1633); the example pom stays pinned to the
released SDK until that ships.
