"web" group doesn't control access to the web user interface

[gtmills]

https://gerrit.openbmc.org/c/openbmc/bmcweb/+/50835 is mapping these groups to Redfish. The "web" group doesn't appear to do anything. The "redfish" group controls access to the web interface.

From https://github.com/openbmc/docs/blob/master/architecture/user-management.md#supported-group-roles

web | Users in this group are only allowed to use webserver Interface
