project_panel: Automatically open project panel when Rename or Duplicate is triggered from workspace (#34988)

In project panel, `rename` and `duplicate` action further needs user
input for editing, so if panel is closed we should open it.

Release Notes:

- Fixed project panel not opening when `project panel: rename` and
`project panel: duplicate` actions are triggered from workspace.
