Canonicalization for 're'-inherited methods

還沒有人認領這個 Issue。

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.

首先找到重新導向／正規化腳本，並比較它對繼承的 Artist 方法的處理方式與 Sphinx 產生的參照。檢查在 3.4.0 移除文件後，Axes 方法是如何表示的。當腳本將這些方法指向其目前的規範位置，或清楚記錄這是不可能的時候，即表示完成。
