Fixes #11533.

This commit addresses the test failures reported in #11533, for the following tests:

  • json_matrix_test.py::test_from_json_long_structs()
  • json_matrix_test.py::test_scan_json_long_structs()

These failures are a result of #11711. When the JSON parser attempts to read integral struct members from a JSON file, if the parsing leads to an overflow, then the STRUCT column value is deemed null on Databricks 14.3 (i.e. without spark-rapids active). This behaviour differs from that exhibited by Apache Spark versions exceeding 3.4.1.

This commit breaks out the problematic JSON test rows into a separate file, whose read is tested in an xfail for Databricks 14.3. The remaining rows are tested on all versions.

The true fix for #11711 will be addressed later.

Fixes NVIDIA#11533.

This commit addresses the test failures reported in NVIDIA#11533, for the
following tests:
  - `json_matrix_test.py::test_from_json_long_structs()`
  - `json_matrix_test.py::test_scan_json_long_structs()`

These failures are a result of NVIDIA#11711.  When the JSON parser attempts to
read integral struct members from a JSON file, if the parsing leads to
an overflow, then the `STRUCT` column value is deemed null on Databricks
14.3 (i.e. *without* `spark-rapids` active).  This behaviour differs
from that exhibited by Apache Spark versions exceeding 3.4.1.

This commit breaks out the problematic JSON test rows into a separate
file, whose read is tested in an `xfail` for Databricks 14.3.  The
remaining rows are tested on all versions.

The true fix for NVIDIA#11711 will be addressed later.
