Duplicate and restore project

[somebody1234]

Pull Request Description

• Close https://github.com/enso-org/cloud-v2/issues/943
  • Add buttons in "versions" tab on the right hand side panel to restore and duplicate projects.

Important Notes

• There is an UI issue when restoring a project - the placeholder UI is removed one render tick later than the "list versions" query is refetched, so an extra version appears for one frame.
