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

[MrCsabaToth]

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.
