docs: relax host resource reporting requirement; refresh audit log fields

- worker-health: drop the resource-based tuner requirement for host CPU/memory
  reporting and trim the Go SysInfoProvider example to a minimal worker.Options
  setup, matching how other SDKs document this. SysInfoProvider can now be
  set directly on worker.Options (sdk-go #2301).
- audit-logs: remove the previously deprecated fields (user_email, level,
  caller_ip_address, details, category) from the format spec, deprecate
  request_id with a November 1 2026 removal target, and document
  async_operation_id as its replacement.

 #### Enable host resource reporting
 
 By default, the Go SDK reports `0` for CPU and memory usage in Worker heartbeats.
-To enable host resource reporting, provide a `SysInfoProvider` when creating your Worker.
-You must use a resource based tuner to enable host resource reporting.
-
+Set `SysInfoProvider` on [`worker.Options`](https://pkg.go.dev/go.temporal.io/sdk/worker#Options) to enable host resource reporting.
 The SDK includes a [gopsutil](https://github.com/shirou/gopsutil)-based implementation via the [sysinfo](https://pkg.go.dev/go.temporal.io/sdk/contrib/sysinfo) library that supports cgroup metrics in containerized Linux environments:
