Bump Redfish schemas to 2023.3

Redfish released 2023.3 1/25/2024.
https://www.dmtf.org/content/redfish-release-20233-now-available

It is several new schemas and added properties to a pile of schemas.
One use case is: ComputerSystem v1.22.0
Added EfficiencyFavorPower and EfficiencyFavorPerformance to PowerMode
https://gerrit.openbmc.org/c/openbmc/phosphor-dbus-interfaces/+/69122

This is a one line change to scripts/update_schemas.py and then ran the
script.

Tested: See the new schema versions (e.g. System 1.22.0).
        No new Validator errors on p10bmc.
