Backend does not support store references

[zeljkot]

Describe the bug A clear and concise description of what the bug is.

If I try to create custom type that contains set of store references, backend complains that it does not support store references.

Code that creates field:

FieldDefinition.of().apply {
    name = "marketplaces"
    label = LocalizedString.of().apply { setValue("en", "Marketplaces") }
    required = true
    type = CustomFieldSetTypeBuilder.of()
        .elementType(CustomFieldReferenceType.of().apply { referenceTypeId = ReferenceTypeId.STORE })
        .build()
},

Error:
