[website] redirect to hash tag link after search

[LuckyPigeon]

At current website, we can only go to the link after search, and scroll down to the keyword page by our own. I think it would be convenience if we add hash tag redirect link. Such as, https://jotai.org/docs/advanced-recipes/large-objects#focus-atom, if we search the tag Focus Atom of Large Object

This highlights an important issue. I think we should include both individual sections as well as entire pages in search results to help users get to the right place. Thanks for the suggestion, @LuckyPigeon.
