PR summary

Added code to test_datetime.py in order to test Axes.tricontourf as requested in #26864
Based on my testing, it seems that the tricontourf function does not support the datetime type, therefore I had to first convert it using date2num() to plot it correctly.

I'm new to this repository and GitHub open source contributions in general, I would appreciate if you provide feedback or if you have any suggestions on how I should proceed.

Thank you for finding this.

It is actually the the goal of doing this exercise to find the places where we think we should support unitful behavior but do not.

It appears that actually current main does not error but also doesn't behave correctly either when handed (at least numpy datetime64 arrays) datetimes. I've opened #27499 to track this problem (along with the other tri* methods)

I will block merging this until the underlying problems are addressed.
