Returning correct operation name for DeleteTableOperation

[andreas-grafenberger]

Motivation and Context

This PR addresses the bug reported here: DeleteTableOperation uses OperationName.DELETE_ITEM instead of OperationName.DELETE_TABLE #6760.

Without this fix, DeleteTableOperation#operationName() will continue to return a wrong operation name (OperationName.DELETE_ITEM). This is important because the operation actually performs a table deletion, and the reported name can be used by shared framework flows such as routing, logging, metrics, tracing, interceptors, error handling, and tests, where an incorrect value would mislabel the operation and create misleading behavior or observability data.

Modifications

Replaced the operation name returned by DeleteTableOperation#operationName(), from OperationName.DELETE_ITEM to OperationName.DELETE_TABLE.

Testing

Added unit tests for modified operation name (from DeleteTableOperation.java):

• operationName_returnsDeleteTable() - Confirms operationName() returns OperationName.DELETE_TABLE

Added additional tests to increase the class coverage (DeleteTableOperation.java):

• getAsyncServiceCall_makesTheRightCallAndReturnsResponse() - Confirms asyncServiceCall(...) calls deleteTable(...), passes the same request object, and returns the same CompletableFuture.
• transformResponse_returnsNull() - Confirms transformResponse(...) returns null
