Non existent `hacker_news.stories` public BQ dataset is referenced in multiple notebooks

Originally I'm going through the Machine Learning Engineer Learning Path (GDRC), and in the Advanced NLP section of the NLP module ("Natural Language Processing on Google Cloud" https://www.cloudskillsboost.google/course_sessions/2920308/labs/363239) multiple labs reference a non existent public BQ dataset `bigquery-public-data.hacker_news.stories`.

* "Text Classification using AutoML" lab (https://www.cloudskillsboost.google/course_sessions/2920308/labs/363205) in the "NLP with Vertex AI" section - https://github.com/GoogleCloudPlatform/training-data-analyst/blob/master/courses/machine_learning/deepdive2/text_classification/labs/automl_for_text_classification.ipynb
* "Keras for Text Classification using Vertex AI" lab (https://www.cloudskillsboost.google/course_sessions/2920308/labs/363228) in the "NLP models" section - https://github.com/GoogleCloudPlatform/training-data-analyst/blob/master/courses/machine_learning/deepdive2/text_classification/labs/keras_for_text_classification.ipynb

The `bigquery-public-data.hacker_news.stories` which does not exist, I think it's moved to the `full`. There are also 9 notebooks in the `deepdive/09_sequence*` which also contain this deprecated reference. Fortunately the "Text classification using reusable embeddings" lab (https://www.cloudskillsboost.google/course_sessions/2920308/labs/363216 : https://github.com/GoogleCloudPlatform/training-data-analyst/blob/master/courses/machine_learning/deepdive2/text_classification/labs/reusable_embeddings.ipynb) - which is in-between the two labs referenced above, so it comes *after* the AutoML lab - has a hint: the proper dataset probably meant to be `bigquery-public-data.hacker_news.full`.

I'm crafting a PR.
