Updated SQLite Cache

📋 Description

This was originally set to Shared then changed to Private, CMS repo then had this PR umbraco/Umbraco-CMS#16627 which actioned this change, however it breaks the tests and could cause content related issues for users so, we have closed the PR and now want to update the docs to match.
