[SPARK-45706][PYTHON][DOCS] Makes entire Binder build fails fast during setting up

### What changes were proposed in this pull request?

This PR proposes to make entire Binder build fails fast during setting up to prevent the Binder image to be successfully built which it cannot be rebuilt later on the same commit.

### Why are the changes needed?

Binder build is currently broken for Spark 3.5.0:

https://mybinder.org/v2/gh/apache/spark/ce5ddad9903?filepath=python%2Fdocs%2Fsource%2Fgetting_started%2Fquickstart_df.ipynb

Seems like we uploaded PySpark late into PyPI, and the installation steps just slightly ignored the failure (a user triggered the first docker image for Binder, and that's being reused at that time PySpark wasn't uploaded to PyPI).

### Does this PR introduce _any_ user-facing change?

Yes, it fixes the user-facing live notebooks (at https://spark.apache.org/docs/latest/api/python/index.html).
