Deprecate use of DAX NOAA assets in introductory tutorial pipelines

[ptitzler]

Considering that the purpose of the introductory Elyra tutorial pipelines is to enable new users to become familiar with pipeline features it shouldn't be necessary to use notebooks that take (in total) several minutes to run. The assets, which were originally introduced for https://github.com/elyra-ai/examples/tree/main/pipelines/dax_noaa_weather_data are currently also used by these pipelines:

• https://github.com/elyra-ai/examples/tree/main/pipelines/introduction-to-generic-pipelines
• https://github.com/elyra-ai/examples/tree/main/pipelines/run-generic-pipelines-on-apache-airflow
• https://github.com/elyra-ai/examples/tree/main/pipelines/run-generic-pipelines-on-kubeflow-pipelines

The notebooks should be replaced with dummy versions that run in seconds and don't require package prerequisites that might break over time.
