Method missing in ModelFactory with new MPG generator

[live1206]

While generate SDK for Azure.ResourceManager.Quota, QuotaAllocationRequestBase is missing.
Added it back with custom code for now in

azure-sdk-for-net/sdk/quota/Azure.ResourceManager.Quota/src/Custom/ArmQuotaModelFactory.cs

Lines 96 to 106 in 30fa6a7

	// Will remove this custom code while https://github.com/Azure/azure-sdk-for-net/issues/54298 is fixed.

	return new QuotaAllocationRequestBase(new QuotaAllocationRequestBaseProperties(limit, new QuotaAllocationRequestBasePropertiesName(value, localizedValue, additionalBinaryDataProperties: null), region, additionalBinaryDataProperties: null), additionalBinaryDataProperties: null);
