Fix skipping fixed_length_char ORC tests on [databricks] > 13.3

[mythrocks]

Fixes #11528.

This commit addresses the failure of orc_test.py::test_project_fallback_when_reading_hive_fixed_length_char when run on Databricks 13.3+.

This test was skipped with an incorrect reason statement in #9646, to address a failure on Databricks 13.3. That failure was not the result of a data mismatch. It failed because the ProjectExec didn't fall back to CPU. (In fact, with Databricks 13.3 onwards, the ProjectExec is not involved in SELECT * queries.)

As an aside, the same test is now skipped on Databricks 13.3 and 14.3, because the error condition it tests does not fire on those versions.
