Fix stale parameter name in JcTools.drain Javadoc

[thswlsqls]

Description

• JcTools.drain(Queue, int, Consumer) documents @throws IllegalArgumentException if maxExportBatchSize is negative, but no maxExportBatchSize parameter exists; the argument is limit.
• The name is a leftover from the private drainNonJcQueue(..., int maxExportBatchSize, ...) helper removed in Proactively avoid Unsafe on Java 23+ #7691. The thrown behavior is unchanged: the delegate MessagePassingQueue.drain(Consumer, int) throws IllegalArgumentException for a negative limit.
• Javadoc-only change in the internal, non-published :sdk:trace-shaded-deps module; no signature, behavior, or public API change.

Testing done

• Docs-only, test-exempt: no test added; ./gradlew :sdk:trace-shaded-deps:check passed.
