Plugins: Provide a link to searching the plugin directory when no search results are found.

Many new users do not know the difference between managing installed plugins and those found in the plugin directory. This helps with discoverability. The link is not provided in multisite installs because we assume that somebody with that kind of power in a network is experienced enough not to need it. This can always be reconsidered later.

props mordauk for the initial patch.
fixes #29865.
