x/pkgsite: search doesn't find "std"

[rothskeller]

What is the URL of the page with the issue?

https://pkg.go.dev/search?q=std

What is your user agent?

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/116.0.0.0 Safari/537.36

What did you do?

Searched for "std".

What did you expect to see?

The standard library page, with the list of packages in the standard library, should be listed in the search results. By strong preference, it should be the first search result.

Admittedly, the standard library is not a package named std. But Its page has the address pkg.go.dev/std, and it's not unreasonable to search for std and expect to find it.

What did you see instead?

A bunch of third party packages with "std" in the name, but not the standard library.

Perhaps related to #59495.

Also worth noting that https://pkg.go.dev/std exists; I find it surprising that it's not the first result, or an immediate redirect, when searching for std. cc @golang/pkgsite
