ax.set_ylabel('text', fontsize=20) had no effect when using
host_subplot with axisartist.Axes because AxisLabel only copied
the text string and color from the underlying axis label, but
not fontsize. Added get_fontsize/set_fontsize overrides so that
AxisLabel inherits fontsize from the ref artist by default, while
still allowing explicit overrides via label.set_fontsize().

Fixes #28124.
When using
host_subplot(or anyaxisartist.Axes), callingax.set_ylabel('text', fontsize=20)sets the fontsize on the underlyingyaxis.label, but theAxisLabelin axis_artist never picks it up — it only copies the text string and color from the ref artist. So the label renders at the default size regardless of what you pass toset_ylabel.The fix adds
get_fontsize/set_fontsizeoverrides toAxisLabelthat inherit fontsize from the ref artist by default (similar to howget_coloralready works viaAttributeCopier). If you set fontsize directly on theAxisLabelitself, the override is respected.
