Drop support for personal OneDrive folder #530
Description
Content sources with type onedrive must be SharePoint sites, personal OneDrive folders are no longer supported (they were never officially documented anyway).
The sidekick should display a dialog, perhaps including a link to a doc explaining how to rectify. Users should be reminded on a daily basis.
On July 1, 2025, the sidekick will stop loading on personal onedrive folder URLs.
