Subject: [PATCH] [BUG](llm-summarizer): fix output_types key mismatch

LLMSummarizer declared @component.output_types(summary=...) but
returned {"documents": ...}, causing a key mismatch that breaks
pipeline connections using the declared output edge.

Align the declaration to match the actual return key: documents.
