Add OEM field in Assembly schema for FRU

There is an `Oem` object within each element in the `Assemblies` array. Since an Assembly resource can hold multiple assemblies, you'd want to add assembly-specific OEM properties there, not at the root (because that would imply those properties apply to all of the included assemblies).

Got it. Thanks. Sorry for the confusion. I am to add OEM field inside the OEM property, not at the root. Like below:

"@odata.type": "#Assembly.v1_3_0.Assembly",
"Assemblies": [
{
"Name": "Card1/Assembly0",
"Oem": {
"Nvidia": {
"@odata.type": "#NvidiaAssembly.v1_0_0.NvidiaAssembly",
"VendorData": [
"1.0.0"
]
}
},
"ProductionDate": "2023-02-16T06:21:00Z"
},
