Add more HBase batch tests

[trask]

Add current-behavior batch coverage for HBase Table.batch(...). The tests pin empty batch calls producing no span, non-empty batch calls being reported as Multi, and single, same-type, and mixed-type action batches continuing without a db.operation.batch.size expectation.

A follow-up PR will update HBase instrumentation (and these tests) to follow batch semantic conventions.

Pull request overview

This PR refactors the HBase client test suite to add current-behavior coverage for Table.batch(...) ahead of upcoming db.operation.batch.size support. It replaces the two separate testBatchGet/testBatchPut methods with a single @ParameterizedTest driven by a BatchScenario builder, pinning today's behavior: an empty batch produces no span, and non-empty batches (single, same-type, mixed-type) report a Multi operation span with no batch-size attribute. Because traceAssertConsumer uses hasAttributesSatisfyingExactly, the tests will fail (signaling a needed update) once a batch-size attribute is emitted, making this a useful regression guard.

Changes:

• Replaced testBatchGet/testBatchPut with a parameterized testBatch covering empty, single, same-type, and mixed-type action batches.
• Added a BatchScenario builder plus get(...)/put(...) helpers and a batchScenarios() MethodSource.
• Removed the now-unused ROW_5 constant and added required imports (Stream, Row, JUnit params APIs).
