Subject: [PATCH] Show Open/Close Project for mixed selections in Project
 Explorer

The ResourceMgmtActionProvider enablement expression required ALL
selected elements to adapt to IResource or IWorkingSet. This hid
Open/Close Project actions when the selection contained non-resource
elements (e.g., working set headers from Ctrl+A).

Changed the enablement to always activate the provider. The existing
fillContextMenu() logic via selectionToProjects() already filters to
applicable projects and only shows relevant actions.

Fixes https://github.com/eclipse-platform/eclipse.platform.ui/issues/3790
