Added registry.ClientOptLogger documentation based on PR #31833, which introduces this new option to allow SDK users to inject custom *slog.Logger instances rather than relying on global slog state.

Source: helm/helm#31833


// Inject a custom structured logger for diagnostic messages.
// This prevents Helm from mutating global process state, which is
// important when embedding Helm as a library.
if logger != nil {
opts = append(opts, registry.ClientOptLogger(logger))
}

if certFile != "" && keyFile != "" || caFile != "" || insecureSkipTLSVerify {
tlsConf, err := NewTLSConfig(
WithInsecureSkipVerify(insecureSkipTLSVerify),
