feat: store sidebar tab and additional action in query string

Related changes:

* adds "manage-team" sidebar action to trigger LibraryInfo's "Manage Team" modal
* moves useStateWithUrlSearchParam up to hooks.ts so it can be used by
  search-manager and library-authoring
* removes sidebarCurrentTab and additionalAction from SidebarComponentInfo
  -- they're now managed independently as url parameters.

  This also simplifies setSidebarComponentInfo: we can simply set the
  new id + key, and so there's no need to merge the ...prev state and
  new state.
* shortens some sidebar property names:
   sidebarCurrentTab => sidebarTab
   sidebarAdditionalAction => sidebarAction
* test: Tab changes now trigger a navigate() call, which invalidates the
  within(sidebar) element in the tests. So using screen instead.
