What changes were proposed in this pull request?
This raises Spark's minimum supported Pandas version to 1.0.0. If the installed version is below, Spark fails with: "Pandas >= 1.0.0 must be installed; however, your version was ..."
Why are the changes needed?
Some of the Pandas-on-Spark tests do not pass with Pandas < 1.0, see SPARK-37465.
Does this PR introduce any user-facing change?
Yes, users with installed Pandas versions below 1.0 will see failures. Also Pandas 1.0 introduces breaks (listed here) which should not affect Spark's interaction with Pandas, but it might introduce breaks to user environments that get their Pandas version transitively through PySpark.
How was this patch tested?
Existing tests. The Pandas version used in Github actions is 1.3.3. I'll verify tests also pass with 1.0.0.
