Wizard: Use SearchInput component for packages

As a small simplification and also to make the UX more consistent, let's
use a SearchInput widget over the custom InputGroup structure.
The only aspect lost in the process is the `validation` property that
doesn't exist in the SearchInput widget. It however only affects the CSS
styling of the searchbox and renders the 'error' state when there's only
a single character in the box. This may not even be desirable, given
that it's not really an error and that we show a note right below the
input box about this anyway.

This means the search boxes will also be consistent between the
repository and package search pages.
Fixes #3133
