Subject: [PATCH 1/4] Fix numpy 2.4.0 compatibility in create_violin()

Fixes #5461

The 'interpolation' parameter was deprecated in numpy.percentile() and
removed in numpy 2.4.0. It has been replaced with the 'method' parameter
which uses the same values.

Changed all three np.percentile() calls in calc_stats() from using
'interpolation' to 'method'.
