Fix Error log entries to Warning

Some logging entries are categorized as ERROR, but they would better be
as WARNING.

1)
```
$ curl -k -X GET https://${bmc}:18080/redfish/v1/Managers/bmc/LogServices/Dump/Entries/INVALID
{
....
    "code": "Base.1.13.0.InternalError",
    "message": "The request failed due to an internal service error.  The service is still operational."
  }
}%

(2023-06-01 23:29:40) [ERROR "log_services.hpp":665] Can't find Dump Entry
(2023-06-01 23:29:40) [CRITICAL "error_messages.cpp":282] Internal Error \
../../../../../../../../../bmcweb/redfish-core/lib/log_services.hpp(666:36) \
`redfish::getDumpEntryById(const std::shared_ptr<bmcweb::AsyncResp>&, const std::string&, \
const std::string&)::<lambda(const boost::system::error_code&, const dbus::utility::ManagedObjectType&)>`:
```

2)
```
$ curl -k -X GET https://${bmc}:18080/redfish/v1/UpdateService/FirmwareInventory/INVALID

(2023-05-31 15:03:38) [ERROR "update_service.hpp":1010] Input swID X1cd6ce5fZ not found!
```

Tested:
 - Set bmcweb-logging=error to obtain Error or higher logs
 - Run the above commands and watch out logs
 - Redfish validator passed and see whether there are unexpected error or higher level logs
