x/pkgsite: do not show packages of a module at the top level #37788
Description
What is the URL of the page with the issue?
https://pkg.go.dev/search?q=gui
https://pkg.go.dev/search?q=gitea
What did you do?
Searching for GUI packages
What did you expect to see?
A list of modules. Packages and sub-packages of a same module should not show in a scattered manner.
Also, some projects have more than one forks/mirrors and the same packages would show repeatedly, which is confusing.
When searching at pkg.go.dev, it shows all packages and sub-packages of a module and the packages of different modules are interspersed. It makes the result look scattered. I propose that pkg.go.dev only shows modules at the top level and only expands the view of packages of a module when explicitly chosen by the user.
It is probably related to #26827.
