Need to fix internal usage of Axis.get_label.

This overrides `.Artist.get_label`, which is for legend labels, with a new
semantic. It is recommended to use the attribute `.Axis.label` instead.

I've been defensive here and only discouraged but not deprecated this. It's been working for users and I'm not clear whether a deprecation is worth it. We can always add a deprecation later.

Can we get Axis.label documented so this will link?

The way attributes are currently documented - Attributes section in the class docstring (https://matplotlib.org/stable/api/axis_api.html#matplotlib.axis.Axis) - they cannot be referenced. I believe we must swich to something like #28825. But before going full scale, we should test it on Axes in #28825. This is far beyond this PR. I would like to get this PR into 3.10, but don't want to push the documentation restructuring for it. For now, I suggest that literal is good enough and we can do attribute linking when there is time.

It looks like we missed that this broke docs?
