[ws_health_exporter] Fix idempotence test failure

[eduardspa]

Remove redundant daemon_reload: true from the "start exporter service" task. This was causing the molecule idempotence test to fail because daemon_reload always reports changed, even when the service is already running.

The daemon_reload is already handled by the restart ws-health-exporter handler (in handlers/main.yml), which is triggered when the binary or systemd unit file changes. On subsequent runs where nothing changes, no handler fires and there's nothing to reload.

This also unblocks the Galaxy publish for 1.10.11.
