LinkedPages 18.0.6

Repo: Jumoo/Our.Umbraco.LinkedPages

Dropped the Umbraco.Cms and Umbraco.Cms.DevelopmentMode.Backoffice package dependencies, so installing it no longer adds the development-mode backoffice to production sites (#51)
Released Umbraco.Community.LinkedPages 18.0.6 to NuGet (release)
