Step profiling in tensorboard_profiling_keras runbook not working

[vignesh-sc]

There is a warning No step marker observed and hence the step time is unknown. This may happen if (1) training steps are not instrumented (e.g., if you are not using Keras) or (2) the profiling duration is shorter than the step time. For (1), you need to add step instrumentation; for (2), you may try to profile longer. when executing the tensorboard view and going to the profile tab in the runbook mentioned in this https://www.tensorflow.org/tensorboard/tensorboard_profiling_keras article. The tensorflow version is 2.11.0.
