Canonicalization for 're'-inherited methods

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.

まずリダイレクト／正規化スクリプトを見つけ、継承された Artist メソッドの扱いを Sphinx が生成した参照と比較します。3.4.0 でドキュメントが削除された後、Axes メソッドがどのように表現されているかを確認します。スクリプトがこれらのメソッドを現在の正規の場所に指し示すか、それが不可能であることを明確に記録できれば完了です。
