Looks like you might need to update your ADMX files to the latest Microsoft Edge ADMX files - https://www.microsoft.com/en-gb/edge/business/download?cs=240449884&form=MA13FJ
Edge now has it's own set of policies broken out from Windows Components.
I would also recommend updating to the latest version of Windows 11 ADMX files as well - https://www.microsoft.com/en-us/download/details.aspx?id=106254
