Update testing docs for MockCommand v9.3.0 API

Update documentation to use new "run" terminology:
- queueResultsForNextExecuteCall → queueResultsForNextRunCall
- startExecution() → startRun()
- endExecutionWithData() → endRunWithData()
- endExecutionWithError() → endRunWithError()
- endExecutionNoData() → endRunNoData()
- executionCount → runCount

Updated files:
- docs/documentation/command_it/testing.md
- code_samples/test/command_it/mock_command_example_test.dart

All tests passing.

 **Key MockCommand methods:**
 
-- **<code>queueResultsForNextExecuteCall(List&lt;CommandResult&lt;TParam, TResult&gt;&gt;)</code>** - Queue multiple results to be returned in sequence
-- **`startExecution()`** - Manually trigger the running state
-- **`endExecutionWithData(TResult data)`** - Complete execution with a result
-- **`endExecutionNoData()`** - Complete execution without a result (void commands)
-- **`endExecutionWithError(String message)`** - Complete execution with an error
-- **`executionCount`** - Track how many times the command was executed
