In 3.4.0, the docs for some Axes methods (pick, pickable, get_picker, set_picker, get_contains, set_contains) were removed. This is because the docs are inherited from the Artist methods.

Sphinx automatically switches all references when generated the docs, but our redirect/canonicalization script here doesn't recognize it. Instead, it thinks these methods were last documented in 3.3.4 and points there.

We should decide if we want to point to the new location (and figure out if it's possible), and do so.
