docs(cache-valkey): fix fictional launcher.Register/health.Register in doc examples (#2)

The package-doc examples showed a fictional launcher.Register / health.Register
API (and launcher.Append as a package func). Corrected to the real wiring:
lc.Append + web/health.NewHandler(...).ServeHTTP.
(component.go doc comment corrected too.)

Documentation-only. No code, API, or dependency changes; version stays v1.1.0
(the v1.1.0 tag is moved to include this fix). Verified by compiling the
corrected pattern against the real API.
